Rohloff Fat Bike Disc Brake Adapter for 180 mm Rotors

Item number: 63724

Dissipate torque with Rohloff support adapters


With all gear hubs, the axle tries to rotate while you're riding. When riding in a lower gear (1-10), the axle wants to turn backwards. When riding in a higher gear (12-14), the axle wants to turn forwards. The torque with which the axle tries to turn is called the support torque. The size of the support torque depends on the load and the engaged gear, and must be absorbed by an appropriate anti-rotation device on the frame. With the simple three-speed hub, a flat-milled axle in the dropouts is sufficient. With a high-performance gear hub such as the Rohloff Speedhub 500/14, the support must be much more stable because of the large gear range.
To transfer the torque of the Speedhub to the frame, support adapters and a matching axle plate are required.

Technology:

Fatbone
The Rohloff Fatbone in combination with the CC-OEM2-190 or A12-OEM2-197 axle plate enables mounting on Fatbike frames with 190 mm or 197 mm dimensions. Furthermore, the frame requires a disc brake mount according to the Direct Post Mount standard (either on the seat stay or on the chain stay). The mounting points of the Post Mount Direct disc brake mount for the brake caliper are used to provide torque support with the Fatbone.

The following conditions must be met for safe mounting of the axle plate (190/197 mm) and the Fatbone: the Rohloff axle plate must lie flat against the frame in the area of the axle plate (R10 / 20 mm) and must not collide with other frame parts (e.g. weld seam). Only then is a trouble-free assembly of axle plate and Fatbone possible. The Fatbone functions as an adapter and thus alters the required brake rotor size to a larger diameter. Mounting on 5" or 8" brake mounts is therefore not possible.

Caution:

Do not use the Fatbone on tandem bicycles!
