Proper's rear hubguards are CNC’d from ULTRAMID nylon and are re-inforced with a heat-treated 4140 chromoly inner for additional protection. Our guard replaces your non-drive side cone nut (all hardware supplied) so there is no need to spread your drop outs.
This guard will fit all nearly all known hubs. It does not fit female hubs with a 17mm axle and 14mm bolts (i.e. GSport Ratchet, Odyssey Antigram, or BSD Backstreet pro).
