At least thats what i think they are called? The rings that goes into the groove at the top of the forks. My bike did'nt have any when I got it, I guess my questions are 1. are they necessary? 2. If they are do any fit from other bikes? they seem like quite a simple part but no that easy to get hold of! Any help guys would be appreciated.

thanks
Tim

They just make it easier when refitting the forks, they just act as a stop when the fork reaches the correct place. They are not necessary.

thanks thats great, at least that's one less thing to worry about! just need to be extra careful when installing the fork legs
