How to replace the freehub on a Focus Concept EX wheel
I have a 2012 Focus Mares AX4 with the freehub worn out – it turns only with a lot of friction.
Focus provided a new one for free even though warranty is expired (if you are not so lucky, try if the freehub suggested by Steffen in the comments will work).
However, it took me some time to figure out how to unscrew the old one. I couldn't find any diagrams or instructions online so if you're in the same situation, here is how its done.
- Pull out the axle and bearing balls. The bolt holding the freehub is invisibly placed inside the hub.
- Insert a 12mm allen key from the non-drive side.
- Find a piece of water pipe or similar to extend the allen key, you need a serious lever as the bolt is tight as ******
- The bolt unscrews counter-clockwise as normal but only if you apply serious force (from the non-drive side)
