The two machined aluminum 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 24.00mm spindle diameter cranks (Shimano, Etc.) in Cannondale PF30A (46mm ID, 73mm wide asymmetrical BB shell) frames without the need for any adapters.

Note: FSA MegaExo spindles can be between 24.00mm and 24.07mm in diameter. If your FSA spindle is 24.07mm, this BB will not work! Please purchase our FSA 24.07x37 ceramic hybrid bearings separately.
