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 22mm / 24mm spindle diameter cranks (SRAM / Truvativ GXP) in Cannondale PF30A (46mm ID, 73mm wide asymmetrical BB shell) frames without the need for any adapters.
* Over Bearing Width Dimensions include supplied silicone dust shields.
