Built for Compatibility and Adaptability: This bottom bracket is compatible with both 24mm Shimano Hollowtech II type axles and GXP axles, thanks to the included adapter. Its flexible design makes it an excellent choice for those who value compatibility across multiple crankset standards.

Interchangeable Bearings for Easy Maintenance: With Blackbearing's interchangeable bearing design, there's no need to replace the entire bottom bracket assembly when the bearings wear out. Simply switch out the bearings without removing the bottom bracket casing, reducing maintenance costs and minimizing wear on the frame.

Enhanced Frame Protection: The aluminum cups screw directly into the frame and are secured with an aluminum spacer, ensuring robust alignment. This design minimizes frame stress, reducing the risk of damage during installation and maintenance.

Engineered with high-quality materials, this bottom bracket delivers smooth performance and increased bearing life, so you can enjoy efficient power transfer and reduced friction on every ride.
