- The PM Bone enables a SPEEDHUB, fitted with a PM axleplate, to anchor its output torque to a frame equipped with Postmount direct brake mount
- This torque anchoring system can only be used on 135mm, 142mm, 170mm and 177mm spaced frames with a direct mount for 160mm or 180mm brake rotors
- Axleplate CC PM = for Rohloff SPEEDHUBs with a hollow quick release axle. These can be pre-fitted to new hubs or purchased separately to convert existing hubs
- The PM Bone Is mounted between the brake caliper and the frame itself. As such, the PM Bone acts as a +20mm adapter and thus will require a 20mm larger brake rotor
