Two machined aluminum cups thread together keeping the bottom bracket 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 BB30 (42mm ID 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! You will need to swap the bearings with our FSA 24.07x37 ceramic hybrid bearings.
