CeramicSpeed PF4130 Bottom Bracket – Precision Meets Performance
The CeramicSpeed PF4130 Bottom Bracket is engineered to bring 30mm spindle crank performance to BB86/BB89.5/BB92 press-fit frames with 41mm shell diameters. Whether you’re fitting a Rotor 3D+, 3D30, or 386EVO crank, this bottom bracket ensures a seamless and efficient integration with your frame.
Each kit includes precision-machined cups pre-installed with CeramicSpeed Bearings, offering unmatched smoothness and durability. These bearings feature super round CeramicSpeed Balls rolling on hardened-steel races, minimizing friction while maximizing lifespan. For even greater performance, the Coated version incorporates a 3-micron metallic layer on the races, enhancing hardness, corrosion resistance, and reducing drag even further.
Lightweight, stiff, and built for endurance, the PF4130 delivers the performance edge every serious cyclist seeks—whether on road or trail.

Performance & Maintenance
CeramicSpeed bearings typically generate just 0.3–0.4 watts of frictional drag per set, delivering smoother power transfer and enhanced efficiency. They last at least 3x longer than conventional bearings. The pre-installed All Round Grease can be replaced with Race Day or Long Life Grease to match your riding style and environment.
