CeramicSpeed PF4630 Bottom Bracket

The CeramicSpeed PF4630 Bottom Bracket is designed for frames with PF30, BBright, or 386EVO shells, allowing riders to install a BB30 crankset effortlessly. These frame standards share a 46mm inner diameter with varying shell widths, making this kit the ideal solution for proper fit and compatibility.

Engineered for 30mm Spindle Performance: Built specifically for cranksets using a 30mm diameter spindle, this bottom bracket ensures a secure interface and optimal alignment. The design maintains stiffness and smooth rotational performance, helping riders maximize power transfer through every pedal stroke.

Ultra-Efficient CeramicSpeed Bearing Technology: At its core, the PF4630 features CeramicSpeed’s renowned bearing system, delivering near-zero friction for exceptional efficiency. Super round, super smooth CeramicSpeed balls rotate within hardened-steel races, reducing energy loss and improving long-term durability for demanding riders.

Standard and Coated Bearing Options: Riders can choose between Standard Bearings or the enhanced Coated version. The Coated option applies a metallic layer to the races, making them even harder and smoother. This results in lower drag, increased longevity and superior resistance to wear under harsh riding conditions.

With ceramic precision, low friction and high durability, the PF4630 Bottom Bracket delivers reliable, long-lasting performance across multiple frame standards.
