- The two machined aluminium cups thread together ensuring the bottom bracket remains stable in the frame, increasing bearing life, and simplifying maintenance
- This means no more creaking, smoother operation, longer bearing life, and really quick bearing replacement
- Specifically designed for installing 24mm spindle diameter cranks (Shimano, Etc.) in Cannondale BB30A (42mm ID, 73mm wide asymmetrical BB shell) frames without the need for any adaptors
- Note: FSA MegaExo spindles can be between 24mm and 24.07mm in diameter. If your FSA spindle is 24.07mm, this BB will not work
