CeramicSpeed BB65 Look Bottom Bracket Bearing Kit

The CeramicSpeed BB65 Look Bottom Bracket Bearing Kit is engineered specifically for Look frames using the oversized BB65 standard. Designed to work exclusively with Look’s Zed carbon cranksets, this kit provides the exact bearings required for a secure, high-performance press-fit installation.

Made for Look’s Oversized Carbon Crank Interface: The BB65 designation refers to the 65 mm inner diameter of Look’s proprietary bottom bracket shell. This larger interface allows Look’s Zed cranks to run with exceptional stiffness and the CeramicSpeed kit ensures that the system delivers maximum efficiency with ultra-smooth rotation.

Choose Between Standard and Coated Bearings: Riders can select the long-life CeramicSpeed Standard Bearings, built with hardened-steel races and super-round CeramicSpeed balls for low friction and durability. For those seeking even greater performance, the Coated Bearing option uses the same balls on steel races treated with a 3-micron coating for reduced drag and extended lifespan.

Engineered for Long-Term Smoothness and Power Transfer: Both bearing options minimize friction while improving power transfer through Look’s unique crank–frame interface. Whether used in road racing, triathlon, or endurance riding, CeramicSpeed bearings help conserve rider energy and maintain responsiveness under load.

With unmatched smoothness and proven durability, the CeramicSpeed BB65 Bearing Kit is the ultimate upgrade for Look Zed crank users.
