PF30 Outboard ABEC-3 BB for 24/22mm Cranks (SRAM) - Black

BB Installation

Our PF30 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 (46mm ID BB shell) frames without the need for any adapters.
