- The most common reason is the way the wheel was built. When you build a
- wheel it is possible to turn the nipple and the spoke at the same time. If
- the threads are not lubricated (and even if they were) then you can "wind up"
- the whole spoke by turning it.
- When you shift weight onto the wheel you reduce the tension just enough to
- allow the nipple to turn in the rim. This is usually a stiction type of slip
- so it slips and then grabs. That makes a pinging noise. It should go away
- within 5 to 10 min. of riding. If now then it could be one of the other
- problems mentioned. Either way do a simple squeeze test on your spokes to
- check their tightness and take the wheel out and see if the bearings turn
- freely. Then lift the front of the bike and spin the wheel and see if it
- spins freely. Put the wheel back in and make sure that it does not have
- any side play. Just keep trying things until something does not seem right
- and you should have your problem. But most likely its the spokes.
