Wheels MFG BB30 Outboard ABEC-3 Bottom Bracket

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 24.00 mm spindle diameter cranks (Shimano, Etc.) in BB30 (42 mm ID BB shell) frames without the need for any adapters.
