PROPER REAR HUB GUARD
Fits Proper rear casette hubs and some other ceramic driver hubs like Simple or Colony
Please note: There are 2 types of Proper female rear axles, this hubguard fits the smaller diameter 14mm axles only. The larger diameter 15mm axles have a extension that fits into the drop out that doesn't have threads on it. We can switch axles in the hubs though to make sure you get one that fits.
This guard fits all Proper hubs with 14mm axles.
