Suspension

The eyelet bushes in shocks are designed to wear out before other more expensive bits do! You can usually tell they are worn by there being a small amount of vertical play in the rear of the bike. Failure to replace them can result in wear on the shock itself. Replacement bush kits and tools for fitting them can be obtained from mojo or betd. Replacement is a quick and easy job.

This service is being done on a set of 2002 Rock Shox Duke SL 100mm forks.
It is fairly simple and many other forks from Rock Shox are very similar.

For some reason people seem to be afraid of fettling shocks. There's no need to be. This is a quick and easy service that will prolong the life of your shock and keep it running smooth. The procedure for Fox air shocks is very similar and there is a good video demonstrating it on the Fox Racing Shox website.

Marzocchi forks are famous for working for ages without fettling. However an oil change will make them run smoother and last longer. It's not difficult to do either. This service is being done on a Z150 fork but the Z1s are very similar as are some other Marzocchi forks.
