Evening folks,

I noticed something of a wobble in my rear hub this afternoon, so I guess it’s new bearings time.

Needless to say, there’s nothing in the owners’ handbook to tell me what size these bearings should be! 😕

Do any of you nice, helpful people on here know what size I need?

Although after further investigation, I’m now wondering whether it’s even worth fixing this hub? They seem universally loathed! 🙁

Easy fix once you know how. Rawlbolt works as blind bearing puller.

Thanks Murray, but I don’t think that’s the right model. According to the specs I can find, mine (which came on a 2015 Stumpy 650 Evo Comp) takes 4 sealed bearings, whereas that how to, excellent though it is, is for a model with 2 sealed bearings and 2 loose bearings?

Pretty sure they use 6903’s.

All the Spesh hubs are pretty simple can’t tell you what’s in yours from memory though sorry. Just take it apart and see
Just be aware some of the ones with threaded on ends caps on the drive side are left hand thread
