CyclingCeramic bottom brackets are combined with low-friction ceramic bearings that are more durable than standard bearings. The high quality finish of the bottom brackets enables them to achieve high performance. They have been designed to be lightweight and, thanks to the design of the seals, offer maximum protection.
