The Rotor BB1 BSA ceramic bottom bracket will give you a definite advantage both on the road and off-road. The ceramic bearings, combined with new contact-free labyrinth seals, ensure optimal smoothness by reducing friction. It is also a reliable choice for any type of cycling, offering unrivalled protection against dust, water and mud. The new shape of the plastic covers has significantly improved lateral compression and resistance to deformation.

In terms of design, the cups offer a modern look; the combination of smooth curves and sharp angles will add character to your bike.
