- Subject: 1B. A Few Words From the Author
-
- Hi, my name is Vincent Cheng. I have been reading the rec.bicycles.*
- newsgroups for a few years and have been participating on the mtb mailing
- list for about 18 months now. Every week, I see the same questions about
- mountain biking, however, no one has ever taken the time to write a FAQ
- for mountain biking. Since I have nothing better to do, I have compiled
- this little FAQ file.
-
- Now, you might ask... How is this the official Mountain Biking FAQ? Did
- someone gave me permission to make it official? Of course not! No one
- else would take the time to do it, and I'm the first one to actually complete
- the whole FAQ, therefore, this is the official one.
-
- FOR PEOPLE WHO WANT TO USE THIS FAQ FOR THEIR OWN WEBPAGES, PLEASE
- CONTACT ME FIRST. THIS IS COPYRIGHTED MATERIAL AND I HAVE 100% LEGAL
- RIGHT TO THIS.
-
- This FAQ is different from most FAQ's you have seen. Most FAQ's are a
- compilation of articles posted regarding the topics. In this FAQ, most
- of the material are written by myself. The articles are then later
- published on the mtb mailing list for editing and revising. In the
- following sections, the parts that were written by others will have their
- names on them.
-
- I am no expert in the area of mountain biking. I'm only 19 and I have
- only mountain biked for about 3 years. However, I have been involved in
- the technical side of cycling for over 6 years. I have worked in various
- shops and jobs. Because of this, you will see, IMHO, better articles in
- the tech section of this FAQ by me than in the riding section.
-
- I should, however, list my biases about some topics. I ride an older
- suspension fork. I ride without an expensive bike (relatively speaking).
- I ride with top mount shifters and discontinued parts. I might not have
- the latest info on products since I can never afford them, but I try to
- gain as much info as possible by reading, testing, and listening to
- others. Remember that this FAQ is not a product review. I try not to
- list any specific products if I can, however, sometimes it is impossible
- to do without. Please do not get offended if you are wishing for
- something different.
-
- This FAQ is not very complete. If you see a topic that you think should be
- covered in this FAQ, please cross-check the rec.bicycles.* FAQ to make sure
- that it's not covered there. If the article has never been covered, I will
- try to get enough articles together to publish a FAQ section for it.
- My e-mail address is: vccheng@gpu.srv.ualberta.ca Please include the
- words--"FAQ" on your message. e.g. "FAQ--*** info". I have received
- complaints about not replying to some mail, but please be understanding. I
- get over 200 e-mails a day from various people/groups/lists. It is very hard
- for me to fish out the FAQ mails without this "FAQ" subject heading.
-
- Before I end this, I would like to thank Mike Iglesias
- (iglesias@draco.acs.uci.edu) for helping me with the new text format of
- this FAQ. He is the maintainer of the rec.bicycles.* FAQ and he has
- agreed to lend me his wonderful format for me to use. Thanks Mike, I owe
- you one! And to Brian Adams (adams@cs.unr.edu), who edited my FAQ
- so that it is actually somewhat understandable. I would also like to thanks
- all you folks out there in cyberspace who have commented on the FAQ.
- I would especially like to thank the people on the mtb-mailing list
- (mtb@cycling.org, for subcribing info, please see http://www.cycling.org
- and look under mailing lists. read on for more info) The people on the
- list are very helpful to my "quest" for a better FAQ.
-
- Note to foreign readers, I believe the FAQ has been translated into
- French, Finnish, and German. If you would like to translate the FAQ into
- other languages, feel free, but please tell me so that I can keep track.
- Please do not ask me where these FAQ's are located, because I really have
- no idea.
-
- Well...that's all.
-
- Have fun and ride hard.

- than the other.
-
- c) newsgroup
- I will try to post this FAQ once every month on rec.bicycles.off-road,
- and alt.mountain-bike. Just got approved, and the FAQ should be posted
- also in rec.answers, news.anwers and alt.answers.

- Subject: 1D. IMBA Rules of the Trail
-
- International Mountain Bicycling Association has set up a list of rules
- that mountain bikers should follow. Please respect these rules as they
- are what many mountain bikers live by.
-
- IMBA Rules of the Trail
-
- 1. Ride on open trails only. Respect trail and road closures (ask
- if not sure), avoid possible trespass on private land, obtain
- permits and authorizations as may be required. Federal and
- State wilderness areas are closed to cycling.
- 2. Leave no trace. Be sensitive to the dirt beneath you. Even on
- open trails, you should not ride under conditions where you
- will leave evidence of your passing, such as on certain soils
- shortly after a rain. Observe the different types of soils and
- trail construction; practice low-impact cycling. This also
- means staying on the trail and not creating any new ones. Be
- sure to pack out at least as much as you pack in.
- 3. Control your bicycle! Inattention for even a second can cause
- problems. Obey all speed laws.
- 4. Always yield the trail. Make known your approach well in
- advance. A friendly greeting (or a bell) is considerate and
- works well; don't startle others. Show your respect when
- passing others by slowing to a walk or even stopping.
- Anticipate that other trail users may be around corners or in
- blind spots.
- 5. Never spook animals. All animals are startled by an unannounced
- approach, a sudden movement, or a loud noise. This can be
- dangerous for you, for others, and for the animals. Give
- animals extra room and time to adjust to you. In passing, use
- special care and follow the directions of the horseback riders
- (ask if uncertain). Running cattle and disturbing wild animals
- is a serious offense. Leave gates as you found them, or as
- marked.
- 6. Plan ahead. Know your equipment, your ability, and the area in
- which you are riding - and prepare accordingly. Be
- self-sufficient at all times. Wear a helmet, keep your machine
- in good condition, and carry necessary supplies for changes in
- weather or other conditions. A well-executed trip is a
- satisfaction to you and not a burden or offense to others.

-
- Subject: 2. Riding Skills
-
- ------------------------------
-
- Subject: 2A. Basic riding position
-
- -Elbows relaxed, bend at about 90 degrees.
- -Grip the bar firmly, but not too hard. If you see white knuckles, then
- you are gripping too tight.
- -Keep your back straight, at about 45 degrees from the ground surface.
- -Try to "stand" on the pedals. You still sit on the seat, but you
- don't place all your weight on it.
- -When not pedalling, always keep your pedals level.
-
- Others added:
- dmerson@ksu.ksu.edu
- -You may want to add that your grips should be about shoulder length apart,
- but that would only really affect small/large people.
- -You could mention that you can (or may have to) ride with pedals
- vertical
- (&/or with one foot loose) in tight turns.
-
- richard@prl.research.philips.com
- Many people spin their pedals slower than is optimum. Faster feet in a
- lower gear will often give you more speed and less fatigue, although it
- can take some time to get used to spinning your legs ar 90+ rpm.
-
- ------------------------------
-
- Subject: 2B. Turning
-
- -Brake before going into the turn, using both brakes.
-
- If you have a lot of traction:
- -Push the outside foot down and lean to the inside (if you have traction).
- -Enter the corner wide, hit the apex with the bike near the inside edge
- and leave the corner wide.
- -Do not use the front brake if you are turning at the bike's limit. The
- front tire is using all its traction for turning. If you use your front
- brake, it will lose its grip and wash out. A front wheel slide is almost
- impossible to recover. A back end slide is easier to recover. Also, the
- brake tire is doing less work than the front, therefore, you can use some
- of its "spare" traction for braking.
-
- If you are turning on loose surfaces, keep this in mind:
- -This technique involves keeping the bike relatively upright; instead, the
- body is leaned in the direction of the turn.
- -Transfer weight slightly forward. Push down on the outside pedal.
- -Twist your upper body to face the trail. Align your upper body so
- that your upper body is slightly leaning toward the inside of the turn.
- -Push down on handlebar on the outside and pull up on the inside.
-
- Others have pointed out:
- Dave Blake [dblake@eureka.wbme.jhu.edu]
- In loose stuff, steering is definitely the preferred way to turn. This
- is the reason many roadies with good bike skills cannot handle
- tight singletrack very well.
-
- To steer, put your weight on the inside of the turn. Turn your front wheel
- toward the turn, and hold your bike upright. Even if one or both of your
- wheels begin to skid you can easily recover. In contrast, if you lean hard
- through a turn on loose material and either wheel loses traction, you will
- be picking gravel out of your leg.
-
- You almost always want your weight centered between your wheels.
- This means you move your butt further back as the terrain gets
- steeper. Learn to feather your front brake. Let off on the brake
- when your wheel hits an obstacle, and hit it harder when you have
- a smooth even braking surface. Many people do not learn to feather the
- brake, so they put their weight too far towards the rear to keep from
- endoing. This rear weight shift results in too little weight being placed
- on the front wheel, so that you cannot easily steer.
-
- lrtredwa@rdyne.rockwell.com
- I find that the most consistent mistake that I make when turning on
- downhills is to shift too much weight to the rear. This causes the
- front wheel to become too light causing it to wash out :-( If my
- weight is more evenly distributed on the bike, I find that I am also
- in a position to recover if the front starts to wash out (if I'm not
- going too fast) although it is not often I can reover from a front wheel
- washout.
-
- John Stevenson [johnstev@world.net]
- Look at the inside of the turn, not the outside. Your body tends to
- subconsciously point in the same direction as your eyes, so this keeps you
- focused on staying tight in the curve, not straying to the outer edge.
-
- Blaine Bauer [bbauer@cisco.com]
- One thing that I've learned through hard knocks is sharp turning -
- especially in loose soil. We have some trails that constantly wind through
- the woods, and have little room on each side (re: trees).
-
- I've found that negotiating sharp turns at some reasonable speed is easier
- when the seat is an inch or so lower than normal. The trick is to lean the
- bike (but not the rider). This is really just a variation of normal turning.
-
- - Point the inside leg in the direction of the turn (knee away from the
- frame), putting all weight on the outside pedal.
- - Push down on the inside handlebar. At this point almost all weight
- should be distributed between the inside grip and the outside pedal. This
- is much easier with a rigid fork - with a suspension fork, you really
- have to bear down on the handlebar (a grunt may be required!).
- - At this point the bike is leaning under the rider, with the seat
- anywhere from under the thigh to just under the knee. The rider's
- weight is centered over the point where the two wheels are in contact with
- the ground, so there isn't a washout problem even in loose conditions.
-
- This method will feel very uncomfortable at first. Pushing the handlebars
- away from oneself is...well, disquieting. The best way to practice this is
- to do figure-8 turns in a driveway. When you've got it down, hose down the
- driveway and then try it. If you can make sharp turns on wet concrete you
- can do it in loose soil.
-
- ------------------------------
-
- Subject: 2C. Braking
-
- -Most of the braking power is in the front brake because when you apply
- the brake, your weight shifts forward and that gives the front wheel more
- traction.
- -To maximize braking power, shift your weight back when braking.
- -In loose terrain, use more back brake than the front. The front has
- less traction because it is being "plowed".
- -In very steep downhill, move your weight way back, almost sitting right
- on the back tire.
- -A skidding tire will give you no control. Therefore, skidding is a
- very bad practice.
- -There are situation where you don't want to brake
- -Never brake when flying. If you are flying in the air (off a
- jump, drop off, ruts), do not touch the front brake. If you land
- with your front tire stopped, you can expect a huge endo.
- -Don't use the front brake in curves (read turning).
- -When going down hill, don't keep the brakes on. Instead,
- feather the brakes.
-
- Others have added:
- rdexter@xylan.com (Robert Dexter)
- You might also add that the momentum of the spinning wheel can cause the bike
- to pitch if the wheel is stopped by the brakes.
- Bill Rod [smts!brod@msss.attmail.com]
- I don't agree completely. I think this will induce skidding. The front
- brake is the best tool for slowing down under any circumstances. This
- excludes an induced skid in a turn during a race. I do agree that a
- little more pressure should be exerted on the rear brake tho'.
- Robert Dexter [rdexter@earthlink.net]
- My comment applies to stopping the front wheel while in the air
- on a jump. Stopping the rotating wheel while in the air would
- cause the bike to pitch forward a little.
- Bill Rod's comment about not agreeing asumes I mean braking
- while on the ground. You may want to clear that up. My comment
- *only* applies while in the air.
-
- richard@prl.research.philips.com
- -Sometimes consider not braking on a short, technical downhill. If there
- is a safe run out, you will have more control letting the bike run, and
- going too slow on really gnarly stuff can cause more problems than
- floating over it. Save the speed loss for where you have control.
- Of course, if the descent is too long or there is no run out, you can do
- real damage to yourself this way.
- -Environmentally it sucks, yes, but a rear wheel skid can provide rear
- wheel steering, setting you up for a better line into the next bit.
- Note:- most of my riding is done on tracks that are thoroughly churned
- up by horses - the bikes smooth out the mud and _improve_ the condition
- much of the time.
- (Author's note. I highly discourage this, but I'm not here to censor, so
- I must publish this)
-
- ------------------------------
-
- Subject: 2D. Shifting
-
- -You must pedal in order to change gears. When changing gear, pedal
- lightly. It will save your drivetrain from wear and tear.
- -If you have "numbers" on your shifter, don't use them. Instead,
- calculate the gear inches and use that as your shifting guide. You
- should be able to locate a program for this from the rec.bicycle.* FAQ.
- -Shift before you think you have to, e.g. climbing. When you have to
- shift, it might be too late.
- -Do not cross your gears, it will kill it. This means that you do not
- run a big chain ring with the large cog or the small chain ring with the
- small cog.
- -Shift lightly on the levers. There is no reason why you need to press
- the shifters real hard to shift.
- -To save the drive train from wear and tear, make sure it is clean and
- well lubed.
-
- Some added:
- Graham Barnes [barnesg@tierfon.hao.ucar.edu]
- I agree about not using the "numbers", but I'm not so sure that calculating
- gear inches is worthwhile. I've been mtbing for ]5 years, and I've never
- bothered to work out the gear inches for any of the bikes I've ridden, except
- when I was thinking about changing cassettes. Maybe I'm missing
- something, but I always went with the philosophy that, if it's hard to
- pedal, shift down, and if I'm spinning madly, shift up.
-
- John Stevenson [johnstev@world.net]
- It's very unlikely that anything but water and crud are major factors in
- wear of MTB drivetrains. Sure, in theory careful shifting and avoiding
- extreme gear ratios will prolong drivetrain life, but in practice I suspect
- that the damage prevented by these practices is insignificant.
-
- [in regard to gear numbers]
- I go along with Graham here. A better reason for avoiding use of those
- silly shifter windows is that if you're looking at them, you're not looking
- at the trail, which is where your eyes *should* be.
-
- [in regard to shifting before you have to]
- I think this can be better expressed:
- Shift before you have to. For example, when you're climbing, shift into a
- very low gear as you approach and start the climb. If you wait until you
- are about to stall it may be too late to shift.
-
- ------------------------------
-
- Subject: 2E. Uphills
-
- -Shift before you hit the climb. The only way to know which gear is best
- for your terrain is from practice. It is very hard on your drivetrain if
- you shift in the middle of your climb.
- -Seated is better for long distance and/or loose conditions. Standing
- is good for hammering up a short steep section with good traction.
- -If you find you are in too easy a gear, upshift once in the back. Do
- not dump a bunch of gear at once.
-
- Seated Climbing:
- -If you are going to stay seated, move slightly forward on the saddle.
- -Move your head close to the stem to keep the front from coming up.
- -Don't pull up on the handlebar, instead, pull backward with every stroke.
- -Keep your body relaxed, and shoulders square to the trail.
- -Put the bike in a low gear and spin.
-
- Standing Climbing:
- -If you decide to stand up, put the bike in a higher gear. You can't
- spin as fast, but you can apply more power per stroke.
- -Crouch down so that your butt is right in front of the saddle. Your
- elbows should be bent and the chest should be just above the stem.
-
- -For both methods, try to look for the smoothest line and look for slight
- dips on the climb. These will offer you a great opportunity to rest for
- a bit.
-
- Others added:
- Bill Rod [smts!brod@msss.attmail.com]
- I agree in general, but IMHO I would recommend using the middle or big ring
- when standing. I've found standing while using the granny gear causes
- overtorqueing (sic) and hence wheelspin.
- Medek@aol.com
- On longer climbs, alternate the position (standing, sitting) for a short
- period of time. Each position uses a different set of muscles and altering
- the position will give you an opportunity to rest different muscle groups.
-
- John Stevenson [johnstev@world.net]
- Tim Gould's maxim always seems relevant here: "Start easy, finish hard". In
- other words, start a climb in the very lowest gear you have, and shift up
- as you get comfortable. That way you can gauge your fitness and the
- severity of the slope, rather than getting commited to trying to stomp up a
- 1km 20 per cent grade in 36/28.
-
- Long climbs, particularly at high altitude, are places where a stupidly low
- gear will come in useful. I'm talking 20/28 *or lower* here. Here's the
- scenario: you're happily plodding uphill in, say, the 22/28 that is now a
- typical low gear on a Shimano equipped bike. You come to a slightly steeper
- technical section that requires an increase in your effort level. You power
- over the problem, sending your heart hammering into the upper end of your
- anaerobic range. What you could really do with now is an even lower gear to
- allow you to recover, but the idiots who spec most off-the-peg bikes don't
- seem to realise this=8A IMNAAHO 20/28 is the maximum sensible bottom gear
- for a mountain bike that is used in real mountains, and I know people who
- have gone to the current technical limit, 20/32.
-
- Brian Adams [adams@cs.unr.edu]
- -Pull your elbows in on very steep, slow climbs. It helps to keep your front
- wheel from wandering.
-
- Tom Hewitt [hewitt@crayalb.cray.com]
- I'm 44years old, and while slower than most riders, can usually clean hills
- that younger riders more fit don't. In my case the key for climbing really
- nasty long technical hills, is to practice going as slow as practical on those
- sections of lessor technical difficulty. This conserves energy for the
- difficult sections, where all-out effort is required. In addition
- balance in an extreme climbing situation is different from balance in
- a level ground situation, and can only be learned by spending lots of time
- fighting to keep your balance.
-
- Rik Allen [richard@prl.research.philips.com]
- -Standing is better on very technical/slimey climbs. You can move your
- weight around much more to hop wheels over obstacles that they would bog
- down on otherwise. Bunnyhopping sideways out of ruts is almost
- impossible seated. Plan ahead. Keep your body moving smoothly up the
- hill, and make the bike move under you.
- -On climbs with obstacles (wet tree routes) these gears cause their own
- problems. Seriously low gears require too many pedal revs to get over
- whatever is in your way, and you end up moving so slowly that balance
- becomes harder, with more risk of wheelspin or flipping over backwards.
- IMHO, anyway. Less than 24 inches becomes a problem for me getting over
- tree roots.
-
- ------------------------------
-
- Subject: 2F. Downhills
-
- -Keep your pedals level (3 and 9 o'clock)
- -Get your weight back. The steeper it is, the more you move your
- weight. It is not uncommon to see someone riding down a hill almost
- sitting on their back tire.
- -Think positive. I had the problem of thinking I'm always out of
- control, but in reality, I'm not even riding close to my limits.
- -Shift to the middle/large chain rings. This will increase tension on
- the chain and you won't have so much chain slap.
- -Brake with mostly your rear brake. You will still need to use your
- front, but the back is used more often and harder.
- -Braking the wheel until it almost stops spinning is good. Skidding is bad.
- -Steer with your shoulders perpendicular to the path you want to move.
- -Sometimes if you can't ride down some section because it's too bumpy, you
- might want to add some speed.
-
- Others have also said:
- Dave Blake [dblake@eureka.wbme.jhu.edu]
- NO NO NO ! ! !. Your front brake always has more power than your back.
- Endoing is not a real problem if you learn to modulate your front brake
- with the terrain. Less brake over obstacles, and more brake when the
- braking surface is smooth and clean.
-
- lrtredwa@rdyne.rockwell.com
- Always be looking for your line. Identify those spots in the descent where
- it flattens out a little, allowing you to brake harder and "get it back".
- This gives you the ability to "let it go" in the more difficult parts for
- control because your line will take you to the part where you can "get it
- back."
-
- Brian Adams [adams@cs.unr.edu]
- -On long descents, consider temporarily lowering the saddle, making it easier
- to get your butt low (or behind the seat) on steep sections.
-
- ------------------------------
-
- Subject: 2G. Front wheel wheelie
-
- -Practice on level ground with no obstacles.
- -Sit down and have weight slightly forward.
- -Shift to a low gear.
- -Push down hard on the pedal and shift your body weight back and pull
- hard on the handlebar.
- -Spread your knees out and try to keep your weight back. Keep pedaling.
- -If you feel you are going to far back, touch the back brake and you will
- fall back down.
-
- Some added:
-
- toadhall@echo-on.net (SLEW)
- The trick to performing the front wheel wheelie is in finding the balance
- point where you are able to ride on one wheel, and you have pulled back too
- far and will land on your butt. One way to find this threshold point is to
- literally pull back TOO far...and don't worry you won't land on your butt.
- Just make sure your feet are out of all manner of locking devices (toe
- clips, clipless pedals, et al), and when you are ready to do the wheelie,
- pull back as far as you can until you literally fall out of the bicycle...be
- prepared to put your feet down so you don't hurt yourself, and instead just
- run with bike still holding onto the handlebars. It might help to lower the
- seat a bit so the bike can slip through the legs. One of the hardest things
- to do when starting out doing the wheelie is overcoming the fear that you
- will pull too far back. The best way to overcome this is to pull too far
- back then CATCH YOURSELF, then you will have a better idea of where that
- threshold point is where you can balance and ride.

- When racing, if the log is too big to cross with 2H, you might be better

- Subject: 2J. Bunny hopping
-
- Two ways to do this:
- The real way:
- -Level the pedals
- -Compress your body down and also the tires by pushing down and bending
- your knees and arms.
- -When you want to take off, pull the handlebar to your chest and move
- your weight back. This will give you a small wheelie.
- -When you are going up, push the bar up and forward, twisting the grip
- at the same time. While you are doing this, unweight the back end of the
- bike by leaning forward and really extend your arms. The saddle might
- hit your chest, but that's ok.
- -Relax your body before hitting the ground.
- -Land with some weight in the back so that the back wheel hits the ground
- first. Make sure your front wheel is straight before you land.
-
- The SPD/toe-clip way:
- -Again, preload your body by coiling down and pressing real hard down.
- -Instead of doing all the weight shifting, just jump and yank up real hard.
- -Landing is the same.

- -Instead of cranking in a high gear, try spinning in a low gear if the
- water is too deep.
- -If the water is real deep, try ratcheting your pedals by doing quarter
- pedal strokes.
- -Brakes will be much less effective when wet, so watch out.
- -Water can get into bearings and damage them. So don't ride things that

- -After riding through the water, pulse both brakes a few times to scrub

- Subject: 2L. Mud riding
-
- -If it's just a puddle, ride in the center of it to minimize the amount
- of trail damage.
- -If it's deep and wet, spin in a low gear and keep seated so that your
- back end doesn't spin out.
- -Try to put less weight in the front. The front tire might plow into the
- mud, causing you to endo.
- -Pulse both brakes after going through the mud to scrub off the mud.
- -Mud, much like water, can do a lot of damage to your bike, so be
- careful. Also, it tends to wear out the brake pads very quickly.
-
- Other riders also added:
- [rokslyde@sowebo.charm.net]
- Try going though thick mud fast, you will sort of "hydroplain" across it
- which leaves less goop in your brakes and gears, this also has the
- added advantage of getting through it quicker.
-
- Dave Blake [dblake@eureka.wbme.jhu.edu]
- Do not ride through mud if you have another option - the trails should
- come first, except in races. You cannot overemphasize the importance
- of maintaining the trails properly in this day of trail closures.

- Brian Adams [adams@cs.unr.edu]
- -I've had mud gob onto the rear derailleur; the chain then grabbed it and

- Rik Allen [richard@prl.research.philips.com]
- If the mud is short and firmish, stand up tall and stay light on the
- pedals, almost hopping over it. "Think light", and skim over the top.

-
- Subject: 2M. Loose Stuff
-
- We don't get too much sand/gravel here in Edmonton, so I turn to friends on
- the mtb mailing list for help:
-
- Peter Greaves [greaves@ccmail.ram.co.uk]
- Look out for the sand taking the front wheel away from your line.
- Weight slightly forward to keep the steering line straight. Look out
- for hitting this stuff too fast and burying the front wheel - instant
- faceplant. Really sandy trails can tire you really fast - they are
- easier in damp than dry conditions.
- Riding in sand is much like riding in mud or snow.
-
- Doug van Houten (?):
- Keep the front end light and grind away with low gearing.
- If the front end is to heavy, the front tire will sink and you will endo.
- Good places for riding in sand are on lake beaches, river shores, or sand
- volleyball pits.
- In Wyoming, we don't have too much sand either, but do have enough so
- I know how to ride it.
-
- [rokslyde@sowebo.charm.net]
- Sand is a very difficult substance to ride on. Once you get started
- it is best not to stop. Turning on sand is no easy trick. Take the
- turn VERY gradually and do NOT lean. Leaning will simply make you
- fall over. Turning sharp doesn't work either, your front tire will
- simply plow the sand until you stop (or fall).
-
- Sand has the same effect as sandpaper on bikes. It grinds and wears
- parts very quickly. Do not ride a bike you like on the beach.
-
- J. Wesley Prince [wesprince@csra.net]
- I have many hours of experience in the infamous Moab sand pits and have read
- a few mag articles on the subject.
-
- Sand Riding:
- 1. The bigger the meat (tire carcass) the better the ride when it comes to
- sand.
- 2. Have a positive attitude (helps in all technical scenarios).
- 3. Carry as much momentum (speed) into the pit as possible. Try to maintain
- this momentum as best you can.
- 4. Shift down a gear or 2 to prevent bog down. It generally doesn't help to
- stand.
- 5. Get the weight on the back wheel and let the front tire float a bit.
- 6. DO NOT attempt to hold a straight line by steering. The front wheel will
- only dig in and bury you. Allow the front wheel to drift around a bit. Keep
- a light touch on the steering. If you are starting to worry about your line,
- you can try a combo of light steering and weight shifting (one side or the
- other) to correct. Sometimes you will start to drift way off line and will
- need to steer to stay on the path. Try to start early and maintain a smooth
- arc. A quick move will likely fail.
- 7. Use a smooth spin. Power stroking will only break the rear wheel and slow
- your momentum.
- 8. If you ride in a sand infested area, consider going to wax for your lube.
- The sand will stick to the oil and grind away at your drivetrain.
-
- Rik Allen [richard@prl.research.philips.com]
- Snow is similar, but slippier. Stay light on the bike if you can - an
- even weight will help prevent bedding in too badly.
-
- Short stretches you can skim over if you hit them fast with the weight
- at the back. Weight too far back tough and when the back wheel slows
- down as it digs in, your weight will go forward, the front wheel will
- dig in, and over the bars you go. Be careful.

- Subject: 2N. Skidding
-
- -Braking-induced skids are useless. Skidding reduces your stopping power
- and increases your stopping distance. Also, you have no control over the
- wheel that is sliding.
- -Turning-induced skids are useless as well. If you are skidding, that
- means you are riding too far on the edge. There are ways to save a
- turning skid, but I'm not going to put it on the FAQ since skidding is
- not recommended.
- -All skids tend to destroy trails. If you skid a lot on your local

-
- Subject: 2O. Singletracks
-
- -Instead of staring at the edge of the trail, look forward and ahead.
- You will ride straighter that way.
- -You will notice that the middle of the trail is usually rutted. This
- may cause problems during turns if you go on the inside. Instead, try
- taking the outside line the whole turn.
- -Some single tracks are too narrow and too hard to ride. If that's the
- case, don't risk a fall. Walk it.
- -If you ride a lot of single track, you might want to reduce the width of
- the bar to reduce the chance of your hands hitting branches. Also,
- L-shaped barends help a lot.
- -Always wear eye protection. You will need it.
-
- Others add:
- Bill Rod [smts!brod@msss.attmail.com]
- -Don't sightsee, your bike will go wherever you look. "Look at the tree, hit
- the tree"
- -If you are unable to clean an obstacle, get off and climb over it. DO NOT
- ride around the obstacle, thereby creating a braid. This leads to
- erosion and angry Park Managers, not to mention trail maintenance people.
- -On twisty singletrack, try getting your butt an inch or two off the saddle.
- This allows you to more easily use body english for maneuvering the bike.

-
- Subject: 2P. Switchbacks
-
- -Slow down as you enter the turn. Start outside, hit the apex of the turn
- on the inside and leave on the outside.
- -If it's real tight, stick your foot out to pivot your bike.
- -If you are real good, stop and bunny hop the bike straight and ride out.
-
- To this, some added:
- "Sautter, Chris/EUG" [cfsautte@sp-eug.com]
- We have lots and lots of switchbacks here in Eugene, Oregon. Here are some
- things that I do to clean the switchbacks around here.
-
- Downhill:
- Slow down for the corner. It's a lot faster to make the corner without
- dabbing no matter how slow you have to go to do it.
-
- Stay on the uphill side of the trail as you approach the switchback. This
- will allow you to make the widest arc as you turn and prevent you from
- hitting anything at the apex of the switchback.
-
- As you approach slowly, put your weight back and put your outside pedal
- down.
-
- As you enter the corner, look at the exit where you want to go. DO NOT
- look at the 100' drop-off that you will fall down if you don't make the
- corner!
-
- With your weight on your outside pedal and slightly back, the next step is
- to commit to the corner. Lean hard into the corner until you are almost
- falling to the inside. When this happens, ease off the brakes and let the
- your bike roll under yourself. This is actually really easy to do once you
- get started.
-
- If you have a hard time with this last step, you can quickly modulate the
- brakes to adjust your balance. It works really well.
-
- When you have passed the apex of the corner, you can let off the brakes,
- start accelerating, and prepare for the next switchback.
-
- You should never skid around a switchback. You have less control and rip up
- the trails.
-
- Uphill:
- For uphill switchbacks, you take the same line as for DH switchbacks.
-
- Approach the switchback with your bike on the extreme DH side of the trail
- so you can make the widest arc possible. Keep your weight centered.
-
- Lean hard into the corner and pedal your bike under yourself so you don't
- fall to the inside. The trick is to commit to the lean.
-
- By the time your bike is under you, you are around the switchback. Cool.

-
- That's not a tail whip. A tail whip consists of putting all your weight
- on the front end, and spinning the tail around the headset. Of course,
- this is not possible AT ALL if you have brake cables.
-
- What Michael is thinking about is (was, in my day) referred to as a
- kick-out. It has no practical use in BMX riding or racing. There is one
- freestyle trick using the kick-out: on PAVEMENT, lock up the front end
- while kicking out the rear. As the back end is moving around, lock up
- the back wheel. When it lands, immediately pull the front end, spinning
- around the back wheel. If successful, you'd have done a 360 now, and
- can continue riding on (or lock up the front end and continue on to
- 720s, etc). Note! With ANY speed, momentum will carry you in the
- ORIGINAL direction. Kicking out to 180 will leave you rolling
- backwards- kicking out any less will probably cause you to highside.
-
- It's not a move I'd recommend at any level of riding ability. You might
- 1. taco your rim (and possibly your whole rear end).
- 2. get thrown off the bike (into those trees that define the
- switchback).
- 3. hit a perfect 180, and (going fast) end up rolling backwards and #2.
- 4. hit a perfect 180, and (going slow) end up at a complete stop, and
- get plowed into by the rider behind you who's using a more conventional
- technique.
- 5. get hurt.

-
- In freestyle a "tail-whip" is done by stopping the front wheel and rotating
- the frame around the headset, while keeping your body above the front wheel/
- handlebar area. (A trick I almost mastered before school got in the way.)
-
- The maneuver described above doesn't have a flashy name that I know of (I just
- use "front wheel 180") but it IS much easier on the BMX/freestyle bike. On my
- freestyle bike I can do 180+ degrees easily, but on the MTB I can barely make
- it to 180 degrees. No wheel damage yet... :-) I've tried this only in a
- parking lot, not on the trail. It's easier to go backwards after the 180
- than to stop and go back the way you came.
-
- Hints: Keep a little speed, just above walking pace
- Start with pedals level, outside foot forward (if back end is swinging
- to the left, put left pedal forward)
- Start turning into the spin, grab BOTH brakes (keeps the pedals from
- moving on you), unweight the rear wheel, and turn
- Push forward on the outside bar and pull down and back on the inside
- use your rear/inside foot to help pull the back end around
- As you set the back end down, let go of the rear brake (or both if
- you want to roll backwards)
-
- ] ... IMHO, it's not worth it try to tail-whip around a switchback ...
-
- Depends on how open the sides of the trails are. Very easy to hit thick brush
- alongside the trail, but if it's open enough it'd work. Probably best done
- on the uphill loop only. :-) I'd probably go for the trials-style hop and
- twist if I couldn't ride the corner. Just stop mid-turn, start hopping for
- balance, and then rotate until you're headed the right direction and ride
- away again.
-
- J. Wesley Prince [wesprince@csra.net]
- Going Down: (Without a nose wheelie) Weight as far rearward as possible.
- Getting off the back of the saddle and with the butt down low is sometimes
- necessary. Swing up on the upper part of the switchback to enlarge the
- turning radius as much as possible. Use both brakes, you will need a lot of
- front brake to prevent a rear skid so keeping the weight rearward and on the
- pedals will help prevent a wheelie. You should concentrate on crouching on
- those pedals thus keeping as little weight as possible on the bars. Turn the
- wheel as steeply as you need to in order to keep the bike on the trail. At
- this point it becomes a balancing act. Too much weight on the outside and
- you go crashing down the hill, too much on the inside and you fall in that
- direction but at least not very far. If you must err, err to the inside. If
- you keep the front tire on line, the back will follow. You will find that
- you can turn much more sharply than you at first believe, just maintain that
- balance and force the turn, the bike will do the rest.
-
- Wheelie Method: This must first be mastered on level ground, then gradually
- increasing slopes on grassy hills. The idea is to grab the front brake and
- push forward on the bars raising the back wheel off of the ground. You then
- twist your lower body, basically rotating the rear of the bike along the
- axis of the headset as the front tire remains pointed in the original
- direction. As the back wheel is about to land, quickly align the front wheel
- with the rear of the bike and pedal away. Obviously this is a skill which
- takes some practice to master (on the open grass prior to trying on the
- switchback). First try to master balancing on the nose wheelie prior to
- trying to turn.
-
- Going Up: Usually more of a challenge. Again, swing a little toward the
- downhill side to give yourself as much radius as possible. You usually need
- to be in the lowest gear. As you start up, you will lean slightly toward the
- inside and keep steering on track. You should lean hard enough that if you
- were to stop pedalling, you would slowly fall over on the inside (which is
- what you will do if you slip or screw up!). The interesting part is that the
- driving force of your pedalling will actually hold you up. If the turn is
- very tight and the climb is very steep you will need a nice low granny and
- really need to crank it hard. To prevent yourself from doing a wheelie you
- may need to edge your weight forard. If you try to stand it will sometimes
- screw up your balance but if you are having trouble using the seated method
- it's worth trying. Also if you are a technical wizard you can try to wheelie
- halfway up and whip your tire over to the right line to finish the turn. I
- have usually found that this is only needed in the extremely sharp turned
- switchbacks on narrow trails.
-
- One more final bit of advice, you must, in your mind, visualize yourself
- making the move before you actually try the move. I have found that this
- proper frame of mind helps more than anything else with pulling off
- technical moves.
-
- Rik Allen [richard@prl.research.philips.com]
- (regarding tail-whip)
- It is a useful move in trials or very twisty singletrack - there are
- plenty of places I know where the bike cannot turn tighly enough with
- both wheels on the ground. You can either get off and walk the bike
- round, tail whip round (an endo with the weight to one side), or just
- come to a halt (track stand), and hop round.
- I've not taco'd a rim doing that in many years, and I can suggest many
- other ways of falling off. Learn by doing endos first, then shift the
- weight a little to the side and the bike will swing that way while the
- tail is in the air. Lower it down with your legs, rather than just
- releasing the front brake whilethe tail is still swing.

- -Stop the bike gently and turn the wheel toward the upslope.
- -Without using the brake, use your balance to try to stay up and not move.
- If you are going to fall toward the bottom of the slope, increase pressure

- Subject: 3B. Clipless Pedals
-
- -Clipless pedal riders are connected to their bikes by cleat and
- mechanical "hooks". There are many pedals out there on the market, each
- with their own designs. In this FAQ, I will NOT recommend any specific
- model because the technology changes too fast for me, and also it has a
- lot to do with personal preference.
- -Advantages: Very solid connection from the bike to the rider. Once the
- rider is experienced, it will be easy for him/her to unclip. It's cool.
- It helps many to bunny hop (read:hop/jumps).
- -Disadvantages: Cost. Fear of being clipped in when you need to remove
- your feet. Must be used with cycling shoes.
- -Float is the amount of side to side movement the pedals allow before
- releasing the cleats.
- -To engage, simply step into it and one of the hook/bars/clips will snap
- back. You should hear a "click" when you are in place (except ONZA).
- -To disengage, twist the foot inward or outward to release, again, you
- should hear a click (except ONZA).
- -When first learning, it is best to set the pedal to the lowest release
- tension. This way, beginners can clip in/out easier.
- -Practice on a grass field so that when you fall, you are not going to
- get hurt. Ride around on the grass and try to engage and disengage each
- foot. Leave the non-practicing foot unclipped in case you fall.
- -Do not ride on the streets/trails until you have mastered these skills.
- -Turn up the tension as your skills increase.
- -Try lubing all the contact points between the pedal and the cleat and
- also all moving parts to improve the smoothness of engagement and
- disengagement.

-
- John Stevenson [johnstev@world.net]
- On current Shimano brakes (that is, ones with a link wire) the most common
- brake set-up error I see is that riders replace their blocks, pushing the
- stud all the way into the clamp on the cantilever body, then pull the cable
- through so that the brake works. Problem is, this leaves the link wire and
- brake cable pointing skyward at a very acute angle, an arrangement which
- results in very low mechanical advantage at the brake, in other words lousy
- braking; a very 'hard' feel at the lever with very little braking power
- unless you really haul on the brakes.
-
- These Shimano brakes should be set up so that the cable and link wire form
- at least a 90 degree angle. More will increase braking power still further,
- but at the expense of a spongy feel and need to set the blocks very close
- to the rim.

- [note from the author]
- To get the best angle with the straddle wire, whether it is the conventional
- straddle wires or Shimano's hangers, you can use the older generation of the
- Shimano Pro-set tool. It holds the brakes together while you tighten the
- nuts/bolts. This works because the older style cantilever brakes are much
- less upright and require a greater angle in the straddle wire.

- Brake boosters help by preventing brake boss (mounting stud) movement.
- If you have powerful brakes on a soft frame (Ti), they will move
- alot. If you have weak brakes on a heavy steel frame, you probably
- won't notice a difference.
-
- To check your frame for brake boss flex, hold the brake bosses between
- you thumb and index finger and apply the brakes (with your other hand
- dummy:-) Did the bosses move much? If not, maybe you first need to
- optimize your brake adjustments and replace frayed or kinked cables.
- In other words, a brake booster is the last thing to add, only after
- you've checked eveything else. It's not a panacea for poor brake
- adjustment.

-
- Subject: 3D. Shifters
-
- There are 3 main types of shifters. Shimano's Rapid Fire plus, Sram's
- Grip shift and Top Mount thumb shifters from various companies.
-
- 1) Rapid Fire Plus
- -The system has a built-in brake lever, so if you buy the shifter, you
- must use Shimano's brake levers (you can use a shifter perch on the
- higher-priced models). This will be changed in 1996.
- -A shift to the smaller ring (front and back) is done by a pull of the
- index finger. A shift to the larger ring/cog is done by pushing the
- button with your thumb.
- -Advantages: Most claim that the RF+ keep their hands in fairly natural
- position. They don't have to move around to shift/brake. The shifting
- is very smooth, especially when matched with a rear derailleur made in
- the same year. Some feel that the optical display is very useful.
- -The disadvantages: Heavier than topmounts/grip shifts. More
- expensive. You can't buy your own brake lever (shifter perches are
- exceptions). Some feel that using Shimano parts is a "shame". Some feel
- that the optical displays are crap. Downshifting in the back is limited
- to about 3 gears and upshifting is only one gear per push.
-
- To this, some added:
- John Stevenson [johnstev@world.net]
- Only XT will have separate RF+ units for 1996. All other groups are still
- "integrated". Perches are available from various vendors for both early RF+
- (without 'Optical Gear Display' windows) and for OGD RF+ units.
-
- 2) Grip Shift
- -There are many designs, the most popular one is made by SRAM.
- -These are shifter units made to mimic the "twisting throttle" motion of
- a motorcycle. Comes in shifter units only, you must supply your own
- brake levers. In 1996, they will introduce their own brake lever/shifter
- units and also they will make shifters that are only compatible with
- their own rear derailleurs.
- -To shift to larger ring/cog, roll your wrist forward. To shift to a
- smaller ring/cog, roll your wrist backward.
- -Advantages: Cheap. Light. Simple. Natural hand position. Easy for some
- to use because of their motorcycling background. Simple to overhaul.
- Great customer service. Favored by many new riders and some experienced
- users. Can shift through all the gears in one twist.
- -Disadvantages: Unwanted shifts can occur when going over bumpy trails.
- Some people don't like the hand rolling motion. Cable routing can cause
- some novice mechanics trouble. Cannot brake and shift at the same time.
- Might be troublesome if used with conjunction with Shimano Light Action
- rear derailleurs. Cannot fit on some multi-position handlebars without
- cutting the barrels (voids the warranty).
-
- Some added:
- John Stevenson [johnstev@world.net]
- SRAM's Grip Shift is a shifter unit which turns only a portion of the gips
- - roughly one-third, depending on how long you cut your grips. Campagnolo
- tried and abandoned a full grip shifter, SunTour produce a 'partial grip'
- shifter like Grip Shift, as do Sachs.
-
- SRAM's 1996 range includes one combined shift/brake unit, aimed at low end
- OEM use. The top end SRT 900 shifter is claimed to be only compatible with
- the 900 rear derailleur. The mountain bike community usually treats such
- claims from manufacturers with scepticism.
-
- [With regard to Grip Shift problems]
- Massive problems in wet conditions: poor sealing means that mud rapidly
- erodes the internals, leading to mushy shifting; can be very dificult to
- grip when wet and muddy; 1995 models with 'Fastest Front Shifting' require
- considerable hand force to shift on some bikes - very dependent on quality
- of cable set up and smoothness of routing.
-
-
- 3) Top Mounts
- -Separate unit from the brake lever.
- -To shift to a larger ring/cog, you push the lever forward, and back to
- shift to a smaller ring and cog.
- -Advantages: Simple, no real moving parts. These shifters last for a very
- long time. Equipped with friction mode so that you can ride with a mal-
- adjusted derailleur. Light and usually cheap (if you can find them).
- Favorites of many more experienced riders.
- -Disadvantages: Very hard to find. Shimano discontinued their shifters in
- 1994 and Suntour is not in business in North America. You need to move
- your thumb out of its "natural" position to shift. Some feel that moving
- their thumb after a long ride is very tiring. Not very "trick".
-
- Final words: With the amount of research going into shifters, all 3 (top
- mounts, RF+, GS) shifters are great. They all shift very well. They all
- have their own unique strong points and weak points. It is impossible for
- one to say that one type of shifter is superior to another type. The
- most important factor in deciding what to buy is personal preference. Go
- with what you like, you will get great shifting if you put in enough money.
-
- ------------------------------
-
- Subject: 3E. Improving Grip Shifters' rear shifting
-
- -In 1994, Shimano introduced a new derailleur called the "Light Action
- Derailleur". This system has a lighter return spring in it, making the
- shifting much mellower when paired with Shimano's own shifters. When
- paired with Sram's Grip Shifts, shifting with the Light Action rear
- derailleurs can be very troublesome. The light action spring might not
- be strong enough for someone to upshift when the bike is not in top
- shape. There are a few ways to fix this problem
- -Install a Bass Worm. It's a rubber tubing that seals the cable end and
- helps the cable to return.
- -Install high-end cables. Gore-tex Ride-on cables are teflon lined
- cables and cable housings that greatly reduce friction and help the cable
- to return. Slick Whip is a lower price version of these cables.
- -Lube your cable with a very dry lube; this should reduce friction (do not
- do this with Goretex Ride-on cables.)
- -Install a Power Spring. It replaces the light action spring with a much
- stronger spring. Your shifting should improve a lot, but it is a pain to
- install for some.
- -Get a pre-Light Action derailleur. Any Suntour derailleur or pre-1994
- Shimano derailleurs should do well.
-
- Some added:
- John Stevenson [johnstev@world.net]
- -Give up using inferior shifters and switch to RF+ :-)
-
- Shimano's 1996 line-up includes a long-arm version of the 105 rear
- derailleur with a non-Light Action type spring. This may also help solve
- this problem, though the track record of 105 mechs on MTBs is poor as far
- as durability is concerned.

-
- Subject: 3F. Brake Squeak
-
- -Check if your brake pads are toed in. This means that the front of the
- pads hit the rims about 1mm before the back.
- -If not, adjust the brake so that the front of the pads is about 1mm
- closer to the rim than the back.
- -If your brakes are toed in, try scrubbing the rims (refer to "increasing
- braking power".)
- -If the problem only appears when the rims are wet/cold, a different
- brake pad might eliminate the problem.
-
- Peat Bakke [pb@europa.com]
- I found that a great way to adjust the spacing / toe in of a break pad is
- with a nickle and a penny. Put the penny between the rim and the front of
- the pad, and the nickle between the rim and the back of the pad.

-
- Subject: 3G. Aheadsets vs. Conventional Headsets
-
- Aheadset:
- -The steerer tube extends above the frame, the stem presses it into
- place along with bearing adjustment.
- -Lighter.
- -Can be easily adjusted and disassembled with allen keys.
- -Easier to steal. To remove the fork, the thief just need to loosen the
- bolts.
- -Riders might bang their knees on stem bolt.
- -More expensive (in some cases.)
- -Lack of height adjustability.
-
- Conventional Headset:
- -The steerer tube is clamped down by the top adjustment cup. The bearing
- adjustment is also clamped down by it. The stem is inserted inside the
- steerer tube.
- -Cheaper.
- -Easier to swap from stem to stem.
- -Less trick.
- -Must have headset wrenches to adjust or overhaul .
-
- Some added:
-
- Blaine Bauer [bbauer@cisco.com]
- I had a normal headset and changed to an aheadset when I put on my fork (but
- only because my original headset was trashed). There are two improvements; a
- normal headset can come loose and has to be tightened regularly, and the
- aheadset stem makes much better contact (I never could get my original stem
- very tight and it tended to swing up to 90 degrees during hairy
- situations...having the handlebars parallel to the front wheel is an
- especially bad thing!).
-
- ]Blaine, you sure that you can't tighten the stem down? I have never had
- ]problems doing that. you just get an allen key and tourque on the bolt,
- ]no trick to it.
-
- Well, my problem was actually that the stem had the adjustment bolt about 2"
- inside the vertical part. I twisted my allen key to the point of bending,
- but this didn't help. Finally I got an allen key attachment for a socket
- wrench so I could really bear down on it, and all was well. That was why I
- wasn't planning on replacing it.
-
- I would recommend that you add that the normal headsets do tend to loosen
- (this is a common complaint especially on rigid-forked bikes). Also:
-
- - Maybe put a paragraph that the best time to convert from headset to
- aheadset is when replacing the fork, but it is by no means an important
- "upgrade".
- At least one convert (me) feels that there was no weight or performance
- difference. Since I got a suspension fork, I suspect that the loose headsets
- would go awaytoo.
- - Mention that it requires a different steering tube (which is why one
- would do this with the fork replacement), a new headset and a new stem.
- Newbees wouldn't be aware of this.

- Subject: 3H. Bar ends
-
- Advantages:
- -Opens up the upper body to improve breathing.
- -Improve leverage on climbing.
- -Helps save your hands/shifters when crashing.
- -Looks cool.
- -L shaped bar ends can shield your hands from hitting branches.
- -More hand positions.
-
- Disadvantages:
- -Good ones are real expensive.
- -Added weight.
- -Some people never use them.
- -Short ones can catch the branches.
- -Might not fit all handlebars, or might crush them if not installed
- properly.
- -Moves all the equipment mounted on the bar closer in.
- -If an end plug is not installed, bar/bar end might be inserted into the
- rider's body.
-
- Position:
- -There is no exact formula for this. If you have never used bar ends,
- try them at 45 degrees first. If you find your hands are too far
- forward, move it up, if it's too far up, move it down.
- -Everybody uses a different angle, from flat to vertical. Most people
- use them at an angle between 45 degrees to 5 degrees up when measured
- from ground. Remember that all these things are very personal, there
- is no point in mimicing someone else just because you think that's the
- way to do it.

- Subject: 3I. Tire Info
-
- This is a letter straight from Panaracer. I asked them for help on the
- topic of tire info since they are one of the more established companies in
- the tire market. Please do not think that I'm in any way associated with
- the company nor do I get profits from this little article. All I know is
- that the article has some great info on tires and, in this case, I'm not
- going to remove the product labels. Remember that this info applies to all
- brands of tires, not just to Panaracer.
-
- Panaracer [Panaracerx@aol.com]
- This is a response to your request for tire information for your FAQ on
- mountain biking. Although this e-mail attempts to answer your specific
- questions, this is not the be-all and end-all on tire information. There
- are issues that are way more complex than what we've written here. For most
- people, this level of information is fine.
-
- [personal info snipped by Vincent Cheng, the author of the FAQ]
-
- Choosing a tire:
- There are so many tires on the market that it is possible to choose a tire
- that's designed specifically for 1) the kind of terrain you ride and 2) the
- kind of rider you are. Most tires are marketed for certain uses, and if
- you're shopping around, these quick descriptions are a good reference
- point.
- For example, if a tire has "SC" (for "soft condition") in its name, it's a
- good bet that it will work best in sand or mud.
- Generally, for looser conditions, a tire should have a more open tread-that
- is, more space between the knobs. When we created the ultimate mud tire,
- the Spike, Panaracer established three main concepts in good mud tire
- design: smaller, non-block knobs, sufficient gaps between knobs, and a
- hard-rubber compound. This design prevents mud from clogging the tire.
- The best way to choose a tire is personal experience-make an honest
- appraisal of the kind of riding you do, then see how well certain tires
- work for you. To help out this process, you can check with experienced
- riders in your neck of the woods. Keep in mind that your tire needs change
- during the year to account for different ground conditions. Also, there are
- many different considerations in a tire's performance-all of which compete
- for your attention. Following are some of these considerations and why they
- matter.
-
- Compound difference:
- The black in black tires comes from the existence of carbon black in the
- compound. Carbon black gives the tire extra hardness and durability.
- Even among black tires, there are differences in the density of the tread
- rubber. Low-density rubber compounds are another shortcut to low weight,
- but they come at the cost of tire performance and durability.
- In recent years mountain bikers have become familiar with so-called
- soft-compound tires. These tires are usually distinguished by their color
- treads. In most cases, these tires lack carbon black in their compounds. As
- a result, their treads are quite flexible, which enables the tire to mold to
- the trail, thereby improving traction in a lot of conditions. The downside to
- this is that the tire can be squishy under load and wear out pretty quickly.
- Panaracer has developed several ways to harness the benefits of soft-compound
- tires while minimizing the drawbacks. The Hard-Core tires have knobs that
- combine a hard interior with a soft, grippy outer layer, giving exceptional
- grip without the usual tread instability or distortion. The Magic tires use
- a unique Binary Function Compound that makes the tread stable in the rolling
- direction and compliant on corners, where you need extra gripping power. As
- a leading tire manufacturer, Panaracer will continue to develop new compounds
- that expand the gripping ability of MTB tires.
-
- [words from the author]
- There are many companies out there that are making the dual-compound tires.
- These tires have a softer compound in the middle and a harder compound on
- the side. These are nice tires as well. Remember that no matter who
- makes the tires, the softer compound tires (in this case the Magic tires)
- do wear down quicker.
-
- Some added:
- J. Wesley Prince [wesprince@csra.net]
- I was referring of course to Slick Rock in Moab, petrified sand dunes
- are the only slick rock I know of and the softer compounds do work better on
- them but don't hold a candle to a completely slick tire, with which you can
- defy gravity on slick rock.
-
- Thread count:
- High-density nylon cord is the choice material for tire casings. A higher
- thread count (like 127 TPI, or threads per inch) indicates a denser weave,
- which improves resilience. Some companies use a thinner nylon cord, which is
- not as tough as regular nylon cord. Compared to regular cord, thinner cord
- does not do as good a job of withstanding forces like hard cornering and
- sharp objects. Thinner cord is lighter, but that's not an acceptable means of
- low weight. (Panaracer tires use regular high-density nylon cord.)
-
- Tread shape:
- The functions of front and rear tires are completely different. A rear tire's
- main functions are driving power and braking, while a front tire's main
- functions are cornering and steering. It follows that the shapes of the
- primary knobs are also different--rear tires use paddle-shaped knobs, while
- front tires counter with arrow-shaped knobs. (Panaracer established the
- front/rear patterns with the Smoke/Dart combo.)
- The complete tread pattern should be designed to give the maximum ground
- contact at any angle--from straight-on riding to hard cornering.
- Some tires alternate the height of the knobs, so that some knobs hook up on
- hard surfaces, then the others hook up in loose conditions.
- Some tires use fewer knobs as a route to low weight. This usually
- compromises tire performance.
-
- [words from the author]
- There are tires out there that perform very well with very little knobs,
- such as many of the Conti tires. Remember, Panaracer is telling us a
- lot about tires, but all from their own research. While they may be
- correct, there are sometimes alternatives to their "methods."
-
- Kevlar/steel bead:
- Ounce for ounce, Kevlar is five times stronger than steel. This high strength
- makes Kevlar a good bead material. Kevlar beads are foldable, and they save a
- lot of weight. All Panaracer mountain bike tires, and many other mountain
- bike tires, are available with both folding and steel beads--the difference is
- 90 grams per tire. This weight savings does not sacrifice performance in any
- way-and if light weight is an important consideration to you, folding-bead
- tires can improve your rides.
- One other bead note: On our new DusterPro tire, Panaracer has developed a
- special bead covering, an elastomer material that helps prevent pinch flats.
- This strip absorbs shock, so when your tire compresses over a sharp bump, the
- tube does not bottom out on the rim, thereby avoiding a pinch flat (otherwise
- known as a "snakebite").
-
- GreenLite tube:
- Lightweight inner tubes represent an efficient way to save weight. Because
- this is rotating weight, it is all the more significant in performance. As
- for durability, it depends--for some riders, light tubes are often superior
- in quality and durability to the standard butyl tubes they replace.
- There are several paths to lightweight inner tubes. One is a lightweight
- butyl tube--but because this is just a butyl tube with thinner rubber, it is
- not as resilient. Another lightweight tube material is latex. Desirable for
- its stretchiness, latex can help give a supple ride. But it also has its
- problems: latex can be fragile and porous, and in the event of a flat, it's
- not easily repairable.
- Panaracer came up with something better in the GreenLite tube. It uses an
- all-new tube material: a strong, supple grade of urethane. The GreenLite's
- low 90-gram weight puts it up there with the lightest MTB tubes. It's supple
- feel helps smooth out the ride. It does not leak air overnight like latex,
- nor is it as prone to failure. And it is patchable with glueless patches.
-
- Some added:
- J. Wesley Prince [wesprince@csra.net]
- Yes latex can be fragile, as it has short life of optimal strength and
- must be replaced after one season, sooner if exposed to heat. They are quite
- wrong however in saying it is not easily repairable. It is in fact the
- easiest tube available to repair since the surface requires no prep besides
- removing talc. It sticks to patch glue much better than butyl.
-
- [words from the author]
- I agree with Mr. Prince here. Latex tubes can be patched, assuming that you
- remove all the talc powder with rubbing alcohol. Remember, glueless patches
- do not last very long. Please don't use them as permanent patches.

- Subject: 3J. Grease/Wax/Oil
-
- I asked the internet expert bicycles for help:
-
- Jobst Brandt [jbrandt@hplabsz.hpl.hp.com]
- That's a large topic. You don't say where these lubricants are to be
- used but I assume you mean wax for chains. Wax does not work and no
- one, but those who believe in the unbelievable, wax chains. Wax is not
- mobile and cannot return to a location from which it has been removed by
- rotation of one part on another. It has little film strength and
- as most adherents of this method admit, it falls flat with moisture
- This exposes its absence from the friction surfaces.
-
- Plain ordinary automotive wheel bearing grease and motor oil is about
- as good a lubricant array as you can find. You can pay more but you
- won't get anything better. The only exception is motorcycle chain
- lubricant that is suspended in a volatile solvent. This allows the
- lubricant to penetrate easily and then gel inside the chain as the
- solvent escapes.
-
- [words for the author]
- While I agree with Mr. Brandt with most things, I don't agree with some
- of his comments. I have been waxing my chain for over 3 years and I have
- had no trouble so far. However, I must say that the wax is useless when it
- gets wet. Also, I do not use straight pure wax, I mix some 10W30 motor oil
- in the mixture.
-
- Also, for grease/oil, I have to say that for most bearing applications, the
- automotive grease is good enough, however, you do not need some of the
- high temperature/high pressure properties of some greases.
-
- For oil, motor oil is good enough for chains, but you can use something
- better. The motor oil is very sticky and can become dirty very easily.
- The newer dry lubes are great if you ride in sandy conditions. The wet
- lubes are very thick, and should stay on the chain after getting very
- wet, but much like motor oil, it tends to get dirty very quickly.
-
- Some added:
- Brian Adams [adams@cs.unr.edu]
- -A time-tested method for lubing a chain: soak a few hours in a pan of hot
- 90-weight gear oil, heated on a hotplate (do this outdoors on the patio.)
- Chris Watts [dvlmask@cinenet.net]
- I feel compelled to adress the chain lubrication issue: Waxing chains is a
- relatively antiquated practice with questionable real world value. Grease
- and bearing oil may be fine for road bikes, but these substances attract
- too much dirt from the trail to be of any real use to mountain bikers. I
- recommend White Lightning. It is a high density lubricant suspended in an
- evaporating solvent. It keeps chains running clean and dry, and works
- great in wet conditions. If you can find it, there's really no reason to
- consider using any other lubricant.
-
- I know you prefer not to use brand names, but White Lightning is the only
- example of this type of product that I'm aware of. (No I don't work for
- them:-) )
- Author's note:White Lightning is a wax like lube. It goes on wet and the
- carrier dries, leaving only the wax behind, inside the links. There
- are similar products out there.

- John Stevenson [johnstev@magna.com.au]
- Preamble: there are no bad materials, only bad applications. Almost any
- material you can think of can be built into successful mountain bike
- frames, providing the engineer who does the design work knows the
- strengths
- and weaknesses of the material, how to use and compensate for them, and,
- most importantly, how to translate those concepts into production
- processes
- that build reliable bike frames.
-
- All materials are available in different grades, with stronger grades
- usually being more expensive. Plain carbon steel, as used for department
- store junkers, has an ultimate tensile strength of about half that of the
- heat-treated alloy steels used in very high-end steel frames.Stronger
- steels make for more expensive frames because, while the raw material is
- relatively cheap, its very strength means that shaping it into tubes,
- cutting and joining those tubes is more time consuming and hence costly.
-
-
- Price ranges
-
- Rather than saying a material is/is not cheap, why not do it like this:
-
- Bike cost ($US): 0 500 1000 2000 4000 8000
- | | | | | |
- Frame materials: <------steel------>
- <---aluminium------------>
- <--------titanium---->
- <----carbon fibre------>

- and so on. You might like to get the right US price bands, as I don't have
- easy access to that info

-
- Bzzzt! 'wastes more energy' definitely unproven, probably unprovable,
- probably untrue. There have been some very long, tedious and circular
- discussions of the whole issue of the actual effect of frame flex on
- efficiency in r.b.tech. Given the calibre of the minds there that have
- failed to reach meaningful conclusions, I think it's safer for you and me
- to leave this one alone rather than repeat folk misconceptions. I will say
- that it's very hard to imagine that, say, Henrik Djernis could have ridden
- steel frames to three world championships if they wasted any significant
- amount of energy. The fact that world titles and world cup races have been
- won on virtually every frame material under the sun implies that the
- differences between materials as far as energy transfer efficiency goes
- are negligible at best and nonexistant at worst.
-
-
- >-unless the frame is very expensive, it's usually heavier than aluminum

-
- >Aluminum
- >-slightly more expensive than steel, but coming down in price

-
- A broken aluminium frame waiting for a free replacement is still a bike
- you
- can't ride. Bit of a bummer in June.
-
- >-slightly harder to weld/bond, but can be done
-
- Actually, quite easy to bond, which is why it's often done in preference
- to welding.
-
- >-very stiff. The ride is rigid, power can be delivered more directly,
- >however, the ride is harsher
-
- It should be said here that this is a property of the application not the
- material. Aluminium is more flexible than steel and has the annoying
- property of lacking a definite cyclic stress fatigue limit. This means
- that however small the repeated stress it is subjected to, an aluminium
- part will eventually fail because of metal fatigue. A steel part, on the
- other hand hand, has a cyclic stress level, below which it will last
- forever. To get round this, designers build aluminium frames so their
- cyclic stress levels are as low as possible to maximise their lifespan. In
- practice this means using large-diameter, thin walled tubes, which also
- happen to be light and rigid. In theory you could also build very light
- steel frames by using thin-walled, large diameter tubes, since the fatigue
- limit stress of good steel is usually higher than that of the aluminium
- alloys typically used in bikes. However, thin-walled steel is hard to weld
- and tends to be rather easy to crush. Aluminium's lower density means it's
- tubes are thicker-walled and less prone to crushing.
-
- >-usually lighter than similarly equipped steel bike
- >-come in all sorts of cool colors and won't rust when exposed to the
- >environment (Note, aluminum will oxidized, but this is differen't than
- >rust)
-
- In certain environments, particularly salty ones, aluminium is prone to
- corrosion. Certain aluminium alloys must be painted or they will corrode
- on contact with air.
-
- >
- >Titanium
- >-one of the most expensive frames, good stuff
-
- Actually the quality now varies almost as widely as steel and aluminium.
- There are some quite inexpensive titanium frames on the market, but they
- tend to use lower grades of material than the 3 percent aluminium, 2.5 per
- cent vanadium alloy that's used by quality builders such as Merlin and
- Litespeed.
-
- >-durability is very good, assuming you find the right builder
- >-it's very hard to bond, if the builder is experienced, the frame will be
- >great. If not, you might be in trouble
-
- Gary Helfrich will be along in a moment to claim that this is bollocks and
- that titanium is only slightly harder to weld than steel and much easier
- than aluminium. Also you're confusing welding with bonding, two totally
- different processes.
-
- >-some frames can be made to have the horizontal stiffness of aluminum but
- >with the vertical flex of steel frames, making this one of the more
- >desirable material.
-
- Sorry, but this is just plain bollocks. Bike frames are damn nearly
- perfectly rigid in the vertical plane, whatever they are built from.
- There's no doubt that there are material/configuration factors that affect
- how a frame feels, but these are probably to do with the way the frame
- dissipates or transmits vibration, rather than the Young's modulus of the
- material.
-
-
- However, if not done properly, the frame can feel
- >dead, much like any other frames
-
- I've never understood what people mean by a 'dead' frame. I suspect it's
- another piece of bike culture folk bollocks.
-
- >-usually about the same weight as the aluminum frames, sometimes a bit
- >more, sometimes a bit less
- >
-
-
- >Carbon Fibre
- >-very expensive also
-
- Priced a Giant carbon fibre bike recently?
-
- >-durability is ok. The fibres can unwoven/break microscopicly by each
- >bump. At the end, the unwoven spot will fail by breaking
- >-it's usually molded
-
- Er, half. Carbon tubes are usually molded, but are then joined into frames
- by bonding into lugs. Trek, Giant use this process and they must account
- of the majority of carbon frames out there.
-
- >-some people find these frames flexy.
-
- Some people can convince themselves of anything in order to pander to
- their prejudices. Which isn't to say that carbon frames aren't flexible,
- no doubt some are, but this is just more repetition of 'lots of people say
- this so it must be true' bike folklore bollocks.

- Subject: 3L. Fork Upgrade
-
- Springs
- -Great for plushness. It takes very little to activate it over the first
- bit, which is great for very small high frequency bumps. It also doesn't
- "stack" as easily.
- -This is the best upgrade for forks with some sort of dampening units.
- Springs are easy to compress, however, it reacts like a pogo stick. If
- the fork is not dampened, the fork might become very bouncy.
-
- Hydraulic Cartridges
- -There are 2 kinds.
- a)If the fork is a normal elastomer based fork, it might be possible to
- retrofit the unit with a hydraulic unit on one side to give the fork some
- dampening.
- b)Some of the newer forks have problem with cartridge leakage. The
- aftermarket cartriges are supposed to be stronger and more leak
- resistance.
-
- Air Cartridges
- -Very plush and provides great dampening.
- -Hard to bottom out
- -Can be a pain to maintain due to leakage. Some users find that they have
- to pump the cartridges very often.
-
- Brake Brace
- -If the fork is too flexy, this will increase the stiffness.
- -Brake bosses will flex less, which is ideal for hydraulic and linear pull
- brake users.
-
- For other fork upgrades that do not involve buying, but rather drilling
- and fiddling, check http://www.magi.com/~kroberge/kmrtop.html and see his
- tech page.

-
- Subject: 3M. V Brakes
-
- Linear pull brakes are nothing new. The Cheap Trick was one of the more
- popular pre-V linear pull brakes. Then came Shimano, with their big
- promotion and racer support, took these brakes from being aftermarket
- equipment to standard OEM parts.
- -Most of the linear pull brakes require more cable pull, normal levers can
- be used, however, it will give the rider a very mushy feel and the
- performance will not be optimal. Keep in mind that a mushy feel usually
- gives you more modulation.
- -96 Shimano XT V brakes had problem with the bushing wearing out too
- quickly, creating loud squeals. A kit is available free of charge from
- your dealer to fix this problem.
- -The main advantage of this setup is that it is much easier to properly
- install the brakes. Because of this, a lot of people believe that these
- brakes are more powerful, but in fact, they were riding with poorly
- adjusted canti's. Check http://www.bontrager.com for more info on how to
- setup the brakes properly. Keith Bontrager has a very good write up on
- how to do so. Kristan Roberge also has a good tech page on this subject
- at http://www.magi.com/~kroberge/kmrtop.html
- -If you are planning to ask whether to buy them or not, and you are going
- to post in the newsgroup, you will receive a lot of messages for cantis
- and a lot for V's. The fact is that most people will probably have an
- easier time with them when it comes to adjusting, but if you want to save
- a few bucks and still get the same performance, cantis will do the trick
- just fine. I perfer cantis, and once you get good at adjusting them, you
- can adjust them better than most v's in about 10 minutes.

-
- I do not have much to offer in this section, so I turned to Peter Greaves
- for help:
- Peter Greaves [greaves@ccmail.ram.co.uk]
- Subject: race tips for FAQ - long
- here it is - from May this year
- 1. INITIAL MESSAGE
-
- me and a riding buddy are going for our first race on 23rd April,
- and we'd appreciate some advice from the list.
-
- fyi, the race is 3 x 5 mile laps cross country - a good variety of
- single track/short climbs/foresty bits etc.
-
- we're both pretty fit and not too bad technically but would like a
- few tips on race preparation (us and our machines!) and racecraft.
-
- any advice gratefully received - we'll post our first race
- experience to the list!
-
- peter "what? ride off THAT? are you MAD?" greaves
-
- 2. REPLIES
- Just a few tips:
-
- -Pre-ride the course the weekend before, if you can.
- -Take it easy the two days before the race. Save your best for the
- race.
- -Start making your bike race-ready NOW. Don't wait until the night
- before the race to install that new chain or whatever.
- -Take an extra tube, chaintool, allen wrenches, pump (I use CO2
- cartridges) and whatever else you think you'll need. Just stuff
- them in your jersey pockets. Funny things happen during races.
- -Always take more to drink than you think you'll need. Camelbaks
- work great in races.
- -Make sure you get to the race site with plenty of time to register,
- get your stuff, put your number on, and warm up properly. Two hours
- before start time isn't too far ahead. You don't want to be rushing
- around just trying to get to the start line.
- -This is your first race. You probably won't win, so don't worry too
- much about your start position. Just try to line up in the middle
- somewhere. Be patient at the start. As you roll off the line leave
- about a wheel-length between you and the rider ahead. That will
- give you enough room to manuver when he and the guy next to him
- lock bar-ends and crash in front of you.
- -Don't kill yourself in the first mile. It's a lot more rewarding to
- pick off people throughout the race who have blown up than to start
- fast, die, get passed by everyone and then barf at the finish. The
- winner won't kill himself in the first mile either. He'll feel
- great. (Hope that's you). Everyone else will die trying to stay
- with him.
- -If someone is following you on singletrack and you can't shake
- them, ask if you're holding them up. Likewise, if you can't get by
- somebody, and the riders ahead are pulling away, don't start
- screaming at him. Just say "Hey dude, can you give me a line when
- you get a chance?" (This doesn't work in Sport class, just Beginner
- and Expert) ;-)
- -If this is a Beginner race, people will be crashing all over. They
- get all excited and try to ride above their ability. Don't crash.
- You can break your bike or yourself and DNF. When in doubt, run a
- technical section. You won't lose time running a technical
- section.
- -Nothing is more disheartening than a DNF. Do everything you can to
- be prepared so you can finish, whatever happens.
- -Most importantly: Have fun!

- http://www.tcinc.com/mtbike/co_mtb.html
-
- First of all, the note posted by Mark was excellent. My brother & I
- have been racing for awhile and all his advice works. One thing I
- would like to add: In regards to arriving early to the race, take
- enough time to warm-up properly. It is critical to get your lungs
- and legs "worked-in". You'll notice the people that haven't
- warmed-up will bonk after hammering full out for the first mile.
- Then valuable time will be lost recovering during the next two
- miles. Since this is your first time, you may be hurting during the
- event, but will be exhilarated when you finish! (Hhhmm - sounds
- familiar).
- Good luck, but more important have fun!
-
- From: Tatum.Mark@tcinc.com
- Let's see what comes to my mind....
-
- * Drink, drink, drink, eat, eat, eat (*before* you get
- thirsty/hungry)
- * Don't get caught in the back of the pack (I tend to be over -
- cautious)
- * Lube it, tune your brakes well (I tuned mine too tight once, so I
- could hardly grab the levers on a rough DH, unsusp.me !)
- * Hows about your bottle cage ( I noticed quite a number of lost
- bottles on the first DH section) ?
-
- My first mtb race was about a year ago, 60 kms. Was on the verge of
- cramping after half distance. Having a blast, though !
-
- Enjoy it !
-
- As for the warming up, any suggestions for that, other than "ride
- around for awhile" which is what I do? I always feel like crap on
- the first climb of the race despite this.
-
- As an aside, in West Virginia they tend to start the races with a
- nice, long climb to let the pack shake itself out before it hits
- the singletrack. Is this pretty much standard operating procedure?
-
- Other tips:
- If you're out of contention - not that I'd know what this was like
- ;) , be a nice guy/girl and stop to help those who were too lazy to
- bring a pump - just make sure you tell them (in a nice way) that
- they screwed up.
-
- Have food/water for after race consumption. Some races provide
- this, but there's almost never enough.

- 3. FINAL MESSAGE BACK TO THE LIST
-
- hiya list!!
-
- a couple of weeks back i wrote for some advice from the list for me
- and a pal who were going for our first (Novice class!) race. we'd
- like to say that the stuff was really helpful, and thanks to all of
- you.
-
- Someone suggested a racing technique FAQ - this would be a great
- idea.
-
- * the most useful stuff from the posts
-
- 1. pre-riding the course. it enables you to pace yourself properly
- on the first lap as well as suss out the obstacles etc.
-
- 2. getting your bike prepped up early. don't leave it to the day
- to find out your spare tube is kaput. (i did - thanks to the LBS
- guys to sort me out with a spare) also having a second tyre set
- would have been useful - my Panaracers were a bit sluggish in the
- sandy soil
-
- 3. keep out of trouble at the start. don't go off in the crush and
- risk a spill/DNF. it's better to catch and pass the guys on lap 3
- - much more satisfying!
-
- * some things we discovered in addition to the useful posts:
-
- 1. talk to other riders before the race about the course - but
- don't let them wind you up about "12 ft drop-offs with broken
- bottles and hungry wolves at the bottom". pre-ride the thing. make
- your decisions about which bits to ride, and which bits to run, and
- stick to them.
-
- 2. don't be freaked out by the tricknology on show. ultimately,
- it's not the bike's name that gets the good spot on the results
- sheet, it's the rider's. we saw loadsa bikes much better than ours
- in the fun race, and we got beaten by guys on lesser steeds than
- ours in our own! and good for them!
-
- 3. if you're coming up to a single-rider technical section, and
- you've got slower riders to pass, either pass them early or hang
- off. there were a couple of accidents where faster guys were
- brought down by accidents to slower riders in front because they'd
- not left enough air for emergencies. also the slower riders would
- spill because of the faster guy being too close!
-
- 4. don't take unnecessary risks in the last lap and ruin all your
- good work!
-
- 5. camelbaks not bottles
-
- 6. this course was about ten big climbs and descents with three
- wooded technical sections. we thought the best plan was climb in
- the granny and use the rear cassette to find your best speed - not
- try to middle-ring everything and blow up. plus, if you've got a
- bit in reserve, you can power over the top of the hill, crank up
- your big ring "widowmaker" and get away fast. we noticed that
- people take breathers at the tops of hills and lose the advantage
- they had from middle-ringing it!
-
- 7. ask people pushing their bikes up hills to let you have the
- best line if you're still riding - they usually will
-
- All-in-all we had a great time - racing really is the thing to put
- some variety into your rides, sharpen up your reflexes, test your
- real fitness level. i wouldn't do it every week, but then i
- wouldn't ride the same singletrack every week either!
-
- 4. HOPE THIS HELPS!

-
- THE DICTIONARY OF MOUNTAIN BIKE SLANG
-
- Compiled by Doug Landauer
-
- There's a little Internet history behind this dictionary. In February
- ('95), Tom Purvis, from Colorado State, posted a message to the
- rec.bicycles.off-road newsgroup that said, in part:
-
- Offroading needs more lore. More culture. More vernacular. [...] Let
- us use the 'net for something really valuable -- let's compile a
- list of bikey slang. Biff, face plant, gravity check, endo; those
- are pretty good terms, but let's get some of the really clever ones.
-
- So a lively thread ensued; and I assume Jerry Dunn made another,
- similar request a bit later. He (Jerry) summarized some of it in
- April, for a book he has in the works...
-
- Thanks so much for all the responses to my request for off-road bike
- slang, for my book ( -- to be published in fall 1995). Here's the
- summary I said I'd post. (Any corrections? Please e-mail me:
- jerryd@rain.org). Thanks for everything! You're a great group of
- people, very helpful, articulate, and funny. All the best -- Jerry
-
- Jerry's summary is in the exact style of, and is almost a total
- superset of, a list that my brother Mike sent me by e-mail in May or
- June (some of the entries were edited down; only one was added). He
- said he'd found his list in the LA Times Sunday magazine. The format
- and wording is too similar to be a coincidence. So ... a question for
- Jerry Dunn, I guess: did the LA Times Mag article appear under your
- byline? (I'm just curious.)
-
- Jerry's original chapter title was "Off-Road Bike Riders Offer a Crash
- Course in Slang".

- Subject: 4D. Mail order vs. Local Bike Shops
-
- -Before buying from mail order firms, check to see if the product is
- really cheaper from them than from your local bike shop(LBS). Make
- sure you add up all the shipping charges. Sometimes some of the LBS
- will match mail order prices.
-
- Mail order, pros and cons:
- -Mail order can be cheaper than buying from LBS.
- -Some mail order companies support local events.
- -Some of them can send you parts faster than a LBS can order.
- -You can't see what you are buying. You must know really what the
- product is. Hint: Run to the LBS and check out the product before
- buying.
- -Some mail order companies are real bad on ordering. They will tell
- you something is in stock, then two days later, they will tell you
- it's on back order.
- -Sometimes your product can get lost/damage in the mail.
- -You have to install the product yourself.
-
- LBS pros and cons:
- -can sometimes give you great deals.
- -They are usually the ones you get advice from, so why not buy
- something from them.
- -You can actually see what you are buying.
- -Sometimes it's real expensive.
- -They might not have what you want.
- -In some areas, the number of LBS's might be limited.
- -Customer service might be even worse than some mail order firms.
-
- Some added:
- Brian Adams [adams@cs.unr.edu]
- Having good LBSs is desirable, so support the good ones when you can,
- even if it cost a little extra. If everyone bought only mail order, there'd
- be no more LBSs. (No, I don't work for a LBS.)

-
- Subject: 4E. MTB Commuting
-
- -The best improvement you can get is installing slick tires. These are
- tires with very little treads and are usually more narrow. If you are
- going to install narrow tires, be sure that your rims can accept them.
- -Install a rear rack. This will help you carry most of your accessories
- without changing the bike's handling characteristics.
- -Remove all removable objects when locking the bike up. Items such as
- lights, seats, and bags should be removed, since they will get stolen a
- lot. If locking up in some very "bad" areas, remove all quick releases.
- -Install fenders to avoid getting splashed.
- -Make sure you have a good lock(s).
- -You can deface your bike, but it doesn't work all the time.
- Professional bike thiefs can spot a good bike from miles away with or
- without the paint/stickers/tags/etc.
-
- Some added:
- Peter Greaves [greaves@ccmail.ram.co.uk]
- -Look for off-road routes to work if you can. use canals,
- backstreets, waste ground. just stay off the roads. If it's a bit
- longer, at least you get the extra training mileage.
- -Don't wear a personal stereo ; it's too dangerous.
- -If you can't be bothered to change tyres (slicks-]offroad) consider
- a cheap set of wheels for commuting. You can also experiment with
- gear ratios too if you go this route.

-
- Subject: 4F. Weight Lifting
-
- Please consult your physician before attempting weight lifting, also,
- please train with another person who is more knowledgeable in weight lifting
- so that he/she can show you the right form for the exercises. Start
- out slow and easy, do not attempt to use heavy weights until your body
- is acustomed to the workout.
-
- Weight lifting is a great way to train for mountain biking. Mountain biking
- is very demanding on the whole body, not just the legs. By strengthening
- the body, the rider can ensure a better ride, with faster speed, better
- control, and less fatigue.
-
- I cannot recommend any specific workout, but I will out line the current
- workout that I have been doing and I have been receiving good results from
- Remember that everybody's body react differently to different exercises,
- please do a little customization on the routine and workout frequency
- to suit your needs. For more info, please refer to misc.fitness.weights.
-
- There are a few common myths about weight lifting. One is that by lifting
- weights, someone might get so muscle bounded that they might not be able
- to have full range of motion, or he/she might be slow. When you look
- at a football player, he is very muscular, but no one is going to call Emmit
- Smith or Barry Sanders as slow. Yes, increase muscularity does restrict
- some motion, however, you can easily counter that effect by stretching
- before, during and after weight lifting. I stretch after my warm up, then
- stretch between sets and after the whole routine is done. My flexibility
- has actually increased. Another myth is that weight lifting can cause
- earlier heart failure. This isagain false. Assuming your heart is in
- very good condition, you should not have too much trouble lifting
- weights, however, I do recommend you to consult your physician before
- starting weight lifting. If you have problems during or after weight
- lifting, stop and seek medical help immediately. Some people
- claim that weight lifting can make them too big and that is usually not
- desired for mountain biking. This might be true to some people, however,
- unless you are genetically gifted, you will not find yourself looking
- like Mr. Universe after a few months of lifting. If you do, please
- consider switching sports to bodybuilding.
-
- OK, the workout that I follow is called HIT, or High Intensity Training. This
- is a very high intensity workout that is done for very short duration of time.
- Instead of doing multi-sets of an exercise, I only perform a few sets,
- however, that set is done to ultra high muscle intensity. For example,
- when I do leg presses, I first warm up, I then put on about 85% of my
- maximum leg press weight on the machine. I then proceed to perform as
- many strict repetitons(reps) as I can. When I cannot continue to do
- more, I quickly remove a little weight and go back and do more. I keep
- doing this until I go down to about 50% of max. When you do all this
- without any real rest, you will be extremely tired. For a more detailed
- explanation, please refer to the HIT FAQ. I only perform the below
- workout twice a week. All exercises are done without rests in between.
-
- The exercises I perform in my workout are the following:
- Stationary cycling for 10 minutes
- light push ups 20x
- light lat pull down 20x
- the above 3 exercises are done to warm up the body.
- Leg Press --1 set of strip set, from 85% of max down to 50%
- Leg Extensions--1 set of pyramid up, from 50% to 100%
- I start by doing as many reps as I can with 50% weight, I then have my
- partner add more plates, and then proceed to do more without more than
- 20 seconds of rest. I keep doing this until I cannot lift anymore.
- Stiff legged dead lift--1 set of 12x
- Calf raises -- 1 set of 20x
- Bench Press -- 1 set of 12
- Lat Pull down -- 1 set of 12
- Bench Press -- 1 set of 8
- Lat Pull down -- 1 set of 8
- The above 4 exercises are done back to back without rest. I usually use
- very heavy weights so that I need assistance when I'm at the 11 reps and
- I have to force myself to do the 12th. Please do not use force reps
- until you know what it is and how it will work for your body(again,
- check the HIT FAQ).
- Military press -- 1 set of 8
- Upright Rows -- 1 set of 12
- Tricep press down -- 1 set of 8
- Barbell Curls -- 1 set of 8
- Wrist curls -- 1 set of 8
- Cruches -- maximum.
-
- All exercises are performed to positive failure, meaning until I cannot
- lift the weight up an inch. This is a very difficult routine for most
- people, so please understand your limits and act accordingly.
-
- I cannot stress this enough:THIS IS MY ROUTINE, THIS IS NOT FOR EVERYONE!
- Check with your physician before starting. Also, READ THE DISCLAIMER AGAIN!

- Subject: 4G. Knee Pain
-
- J Wesley Prince [wesprince@csra.net]
- Below is the reply I sent to Tom regarding his knee pain. Thought you might
- want to consider it as FAQ material for anterior knee pain.
-
- Sorry for the late reply. I am way behind on the list and still trying to
- catch up. Anterior knee pain is generally thrown into a catch-all category
- described as patello-femoral syndrome. A precise description of where the
- pain is located, what makes it better and what makes it worse would be
- helpful. I will make my best guess without the benefit of an exam. Just from
- the most likely diagnosis is patellar tendonitis. Often brought about by a
- sudden increase in training (or a difficult race with mucho gear pushing?).
- It is usually quite benign and easy to treat. I hope it is much better now
- but if not, let me know. For the benefit of yourself and others I will
- outline a treatment / rehab regimen for this disorder:
-
- 1. The pain is your body's way of telling you something is wrong. Therefore,
- the most important thing is to stop (if you are racing, consider stopping
- the race or at least go into spin mode and stop the gear pushing). A severe
- pain means "stop now or you will be sorry!" A DNF sucks but so does
- Arthroplasty and subsequent rehab.
-
- 2. Ice the knee for no more than 20 min (E-mail me if you need an
- explanation for why longer is NOT better when it comes to icing injuries).
- Do this as frequently as possible during the next 48 hrs allowing 1-2 hrs
- between treatments. Avoid walking up stairs and hills and much walking
- period if possible. If there is swelling you can wrap the knee but keeping
- it elevated (higher than the heart or you are not really elevating it) is
- the preferred method. Obviously if you have to go to work, wrapping will
- have to do.
-
- 3. NSAIDS like aspirin, ibuprofen, naproxyn (Alleve) are the mainstay of
- treating musculoskeletal injury. Different substances work better on
- different people. Ibuprofen works as well as all those very expensive Rx
- brands and is dirt cheap to boot. For an acute injury, 10 days of 1600-2400
- mg per day is need. These are not headache doses, but are need for injury
- inflammation. Divide into three doses and take it with food. If you have
- trouble with stomach acidity (ulcers, gastritis) you may cause a bad flare
- up so avoid these meds (tylenol is fine for pain but is useless as an
- anti-inflammatory). If you have kidney disease also avoid these meds.
-
- 4. When you are pain free in normal walking start to easy spin on the wind
- trainer or a nice flat area in a low gear. Just turn the pedals over for
- 15-20 minutes or so the first day. Stop if you have pain. Ice the knee after
- the ride as above for a couple of ice cycles. Progress your riding as
- tolerated, maintaining a pain free workout. If you continue to have pain
- with minimal effort and have done what you were supposed to do (as above)
- it's time to see the orthopedist (a sports medicine specialist if possible).
-
- 5. Cycling overdevelops the middle and lateral groups of the quadriceps
- muscles and virtually ignores the vastus medialis. This is because the
- medialis is resposible for the final 10-20 degrees of extension of the knee
- as well as keeping the patella from tracking too far laterally. To protect
- the knee you should not be extending beyond 15-20 degrees shy of full
- extension in your stroke. You can palpate this muscle on yourself. Feel that
- little bulge above the knee on the inside as you extend your knee. It
- doesn't get hard until almost fully extended (unlike the other groups more
- lateral). You can strengthen this muscle to help keep the patella on track
- by doing straight leg raises with progressive ankle weights. This will help
- to ensure midline tracking of the patella as you cycle and hopefully prevent
- later injuries. Anyone with patellofemoral syndrome type pains should be
- augmenting their vastus medialis. It almost always helps!
-
- 6. You must be fit-kitted unless you are using clips and straps without
- cleats. If you use cleats, take a moto-tool and hour-glass them. If you use
- power-grips, time to go to clipless. It you are clipless, make sure you have
- rotational freedom. The new shimano pedals work well as well as Onza (for
- rotational freedom, not for action). Bee-bops, speedplay and others also
- have good freedom. Ritchey's have pseudo-freedom that is not smooth and in
- my opinion worthless in this regard. Back in early Sept I posted a how-to on
- adding rotational freedom to shimano 737's. If you are interested, let me
- know and I will try to dig it up and forward it (a moto-tool is required). I
- personally believe that everyone should have at least 7-10 degrees of float
- and some absolutely require it. This is easily ascertained while going
- through the fit kit procedure. If the bars float back an forth as you pedal,
- you set the cleat in the middle of the float and tell the person they need
- pedals with float. The more they waver, the more float is needed. Ignoring
- this will most likely send you to the orthopedist somewhere down the road.
-
-
- Disclaimer:
- N.B. (note well) The information provided above is provided without the
- benefit of a physical exam. The Physical Exam along with X rays and other
- studies are sometimes very important for arriving at the proper diagnosis.
- While anterior knee pain is usually quite benign, there can be serious
- etiologies for the pain which demand medical / surgical intervention. Severe
- or prolonged pain, marked swelling about the knee, a locking of the knee,
- any instability of the knee, the inability to bear usual weight on the knee,
- and a knee which worsens or does not improve within 1-2 days of conservative
- therapy needs a prompt medical evaluation. In addition, any popping heard or
- felt at the time of the injury needs prompt medical evaluation.
-

-
- Subject: 4H. What to Carry
-
- A good ride kit is very essential for a safe and fun ride. First thing
- first, don't bring anything that you are not going to be able to use.
- For example, if you don't know how to fix a flat, bringing a patch kit
- will not do you any good. It is recommended that you learn the basic
- skills that are needed for first aid and basic bike repairs.
-
- Items for short ride:allen key and wrenches for all the nuts and bolts
- on the bike, tire levers, pump, patch kit/tubes, chain tool, cresent
- wrench, zip ties, duct tape and a small first aid kit.
-
- For longer rides, you might consider adding cables, brake pads, food,
- water, a bigger first aid kit, crank remover, spare spokes, casette
- remover, and extra clothing.
-
- To carry these items, you can use a fanny pack, jersey pockets, bike bags,
- backpack style hydration systems and so on.
