Brake mounting adapter from HOPE model HBMM. HOPE HBMM adapter is designed for PM mounting on frame, fork and brake caliper.

Thanks to the HOPE HBMM adapter, it is thus possible to increase the diameter of the disc by +40mm than without using the adapter. The adapter is made of very strong aluminium which is milled on CNC machines. The adapter is supplied with M6 bolts for mounting on the frame or fork.
