The Wheels Manufacturing Outboard Bottom Bracket comes with two machined aluminum cups which 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 22.00mm/24.00mm spindle diameter cranks (SRAM / Truvativ GXP) in Cannondale BB30A frames without the need for any adapters (42mm ID, 73mm wide asymmetrical BB shell).
