Right.
20mm axle Fox 36, something like 3-4 years old at a guess, and it’s needed to run a 15mm axle. New hub not an option, and the exirting hub won’t take 20mm (Just don’t ask, OK? Please don’t….)
Fox make a 15mm step down kit for 2015 models onwards, however Mojo tell me this won’t fit pre 2015 models but won’t say why. To the best I can find out from the dimensions available, the internal diameter is within reason and it looks like it might fit.

So, anyone tried it, or does anyone else make a 20 to 15 step down kit that will work?

Cheers in advance 🙂
