High-Efficiency Bottom Bracket for 30mm Spindle Performance

Description

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.

Features

Frame Compatibility: Fits PF30, BBright and 386EVO shells sharing a 46mm ID for precise, secure installation.
30mm Spindle Support: Designed for BB30 cranksets to ensure stiffness, smooth rotation and efficient power transfer.
Low-Friction Bearings: Uses ultra-smooth ceramic balls with hardened-steel races for high efficiency and reduced drag.
Standard & Coated Options: Coated version features a metallic layer for enhanced durability, smoothness and extended life.
Performance & Longevity: Engineered for demanding riders seeking maximum efficiency with long-term reliability.

Technologies

Oversized Bearing Support: 30mm cranks offer high stiffness with low weight, optimized by 46mm ID shells for stable load distribution.
Extended Cup Design: Cups reach deeper into the shell and use a telescoping spacer tube to stiffen and better seal the system.
Ultra-Low Drag Bearings: Standard bearings deliver only 0.3–0.4 watts of friction—about 75% less drag than conventional systems.
Longevity Advantage: CeramicSpeed bearings last up to 3x longer than typical bottom brackets under comparable use.
Tuneable Grease System: Race Day, All-Round, and Long Life greases adjust performance from minimal drag to maximum durability.
Coated Bearing Technology: Metallic layer creates races 75% harder than steel, delivering extreme corrosion resistance and reduced friction.
O-Ring Support System: Compatible with crank setups lacking preload adjusters, ensuring stable fit and alignment.
