What specific 8/9/10 speed free hubs are compatible with my 1992 7 speed 105 hub?
After doing some google/bikeforum searches this is what I think I have so far:
- there are compatible free hubs that can be swapped out pretty easily
- the 8/9/10 free hub is wider to the original 7 speed free hub.
- there will be a need to "re-dish" the wheel after the swap to the new hub
- there will be a need to respace the frame from 126mm to 130mm (or even 135mm) accommodate the new wider hub/freehub
I've got an exciting new bike coming in: a 1992 Bridgestone XO-1 it actually has 26" wheels. Its the model with the side pull brakes and 7 speed 105 drive train (as opposed to the more popular 1993 orange framed version which had cantilever brakes and 8 speed drive train).
I did see that you can fit 650c wheels onto this frame even with the normal caliper brakes.

So I'm more inclined to just re-space the frame to 130mm, keep the original wheels (and modify them with new 8/9/10 speed free hubs) so I have the option to put large tires on them. Then buy another set of 650c road wheels for use in a fast road bike set up.
