Rotor ALDHU 3D+ Axle
The Rotor ALDHU 3D+ Axle can be used with the Rotor ALDHU 3D+ crank arms. There are two options: Rim brake (standard) 147 mm width and for the disc brakes (with offset) 152 mm. At road bikes with disc brakes have a wider rear to keep the chain line in good shape you need a wider axle. In both cases, the Rotor ALDHU 3D+ axle has a diameter of 30 mm and works with most bottom bracket fits. Those fits are: BB30, BB386, PF30, PF4130, PF4630 and UBB30.
