The splined mounting for a Shimano Freehub Body, is it a standard fixing? I've got a cheapy wheel on my commuter bike and the Freehub is a little gubbed. Being lazy by asking you lot as opposed to taking it off for looking for a part number. Just wanting to know if I can just get the "cheapest" 9sp Shimano Freehub Body and it will fit ok.
I'm interpreting your post a little differently to those above. I'm assuming you've got a no-name hub & freehub which you're fitting a shimano cassette to? In which case - the freehub is specific to the hub - and if it's a no-name cheapie hub, it won't take a Shimano freehub.
Best find out who made the hub and try and find someone who stocks an exact replacement.
Also, I had to replace a Shimano XT freehub recently, and found it was cheaper to buy a whole new hub and strip it for parts than buy just the freehub, and I got spare axle, bearings, QR into the bargain.
