  • What size bearings for the main pivot on a Stumpjumper FSR?

    Does anyone know what size the main bearings are for a Stumpjumper FSR. I think its the 2008 120mm travel version.

    Is it easy enough to change them or are any special tools needed?

    Changing the main pivot isn't too bad, the bearings are in the chainstays which makes ensuring they are in straight a bit harder- getting all the spacers etc lined up when re-attaching the back end is the most faffy bit!

    I did the hundreds of little buggers on my epic, I made a bearing press using bolts sockets and various washers. Appears to work ok, only buy decent bearing.
