BB86 ceramic bearings are very hard to find for 30mm crank spindles.
That's why we have designed this BB that will suit with BB86 frames and Rotor cranks: 3D+, 3D Power, 3D Inpower, 3D Flow, 3D30.
The smoothness is unbelievable ! You can expect saving 4 watts at 70 RPM compared with a standard steel BB 41/30.
