PF30 ABEC-3 BB for 24mm Cranks

Wheels Manufacturing thread together bottom bracket for frames using the PF30 bottom bracket standard. 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 24mm spindle diameter cranks (Shimano, Race Face X-Type, etc.) in PF30 (46mm ID BB shell) frames without the need for any adapters.

Note: *Specialized Carbon OSBB frames with a 61mm shell width need additional cup spacers.
