Other features of these brakes are;

  • Geomet coating on hubs, rotors and calipers for corrosion resistance

Unihub

Unihub's entire wheel end (wheel, hub, stub axle and bearing) is optimized to ensure that axial and radial loads are always carried exactly where you want it to be - directly through the bearing centre, on the meaty part of the stub axle). These hubs feature long life, sealed unitary bearing and our new threaded, O-ring sealed dust cap. See more
