The Wheels Manufacturing PF30 and OSBB Outboard bottom bracket will give you all of the same benefits as our 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 22mm / 24mm spindle diameter cranks (SRAM / Truvativ GXP) in PF30 & Specialized Carbon OSBB frames without the need for any adapters.
