The Blackbearing PF30 SRAM B3 Bottom Bracket Bearing Kit is designed for cyclists who demand smooth performance, durability and precise fit. Built to enhance pedaling efficiency, it delivers a seamless connection between your SRAM crankset and PF30 bottom bracket shell.

Perfect Fit for PF30 Systems: This kit includes two precision bearings measuring 31x43x7mm, engineered specifically for PressFit 30 (PF30) bottom bracket shells paired with SRAM cranks. Each bearing ensures accurate alignment and optimal load distribution for consistent power delivery.

Smooth and Efficient Power Transfer: The high-precision construction minimizes rolling resistance and friction, allowing smoother pedaling and improved efficiency. It helps maximize energy transfer from crank to wheel, ideal for performance-oriented road, gravel and MTB riders.

Built from High-Quality Materials: Crafted from premium-grade materials, the B3 bearings offer exceptional durability and wear resistance. They maintain consistent smoothness over long periods, even under tough riding conditions.

Please note, this bearing kit is not suitable for all SRAM bottom brackets. Confirm specifications before installation to ensure compatibility and achieve optimal performance with your PF30 setup.
