The Rohloff PM Bone is an essential accessory for Postmount frames, providing a pickup point for the PM axle plate. Designed to sit between the brake mount and brake caliper, the PM Bone acts as both an adapter and a secure connection point. However, it’s important to note that the PM Bone requires a larger brake rotor size, depending on the frame’s brake design.
Benefits:
- Adapter and pickup point: The PM Bone acts as both an adapter and a pickup point for the PM axle plate, ensuring a secure and stable connection between the frame and the Rohloff Speedhub.
- Compatibility with Postmount frames: Designed specifically for Postmount frames, the PM Bone allows for the installation of the PM axle plate on these frames, expanding the options for using a Rohloff Speedhub.
- Enhanced clearance: By using the PM Bone, frames with Postmount brake mounts can accommodate larger brake rotors, providing increased stopping power and better heat dissipation.
