Wheels Manufacturing Inc. PF30 Outboard Zero Ceramic Bottom Bracket

The Wheels Mfg PF30 Outboard bottom bracket will give you all of the same benefits as their well-loved Outboard style BBs. 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 24mm spindle diameter cranks (Shimano, FSA, Etc.) in PF30 frames without the need for adapters.
