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 offer a lightweight package and, thanks to the design of the seals, allow maximum protection.
