The CEMA Innenlager BBright46 Interlock is a high-quality bottom bracket designed for frames that use the BBright 46 mm standard, commonly found on modern performance road bikes. Built around smooth-running precision bearings, it helps your crankset spin freely and efficiently, reducing friction and improving power transfer with every pedal stroke. The Interlock design is intended to provide a secure, creak-resistant fit in the frame shell, making it an excellent upgrade or replacement option for riders who demand reliability and long-term durability from their drivetrain components.
This bottom bracket is engineered to cope with the stresses of hard training, racing, and everyday riding in all weather conditions. CEMA focuses on robust bearing construction and effective sealing, helping to keep out water and dirt so your bearings last longer and require less frequent maintenance. Whether you are refreshing a well-used bike or completing a new build, the CEMA Innenlager BBright46 Interlock offers a clean, precise interface between frame and crankset, contributing to a quieter, smoother, and more efficient ride.
