- You can often repair stiff
- chain links with oil or careful
- lateral bending. Severe cases will
- require replacement of links.
- Links are replaced in pairs, an
- inner link and an outer.
- 1- and 3-speed bikes use 1/8"
- wide chain, for which you buy
- master links. These snap on
- easily.
- Derailleur-type bikes have no
- master link, all the links are the
- same. For these chains you need a
- chain tool. This tool drives a
- rivet of any link almost all the
- way out of the link, making it
- possible to separate the chain.
- Never drive the rivet entirely

- out, since you will not be able to
- re-install it. After your chain
- repair is complete, simply drive
- the rivet back into position. If
- stiff, bend the link laterally
- (carefully) to make it flexible
- again.
- With care, you can use a
- hammer and a nail instead of a
- chain tool to drive a rivet out.
- If you are putting a new
- chain on a derailleur bike, the
- correct length is the longest
- possible while engaged on the
- smallest rear and smallest front
- sprockets without sagging.
