CeramicSpeed T45 Bottom Bracket for Shimano

The CeramicSpeed T45 Bottom Bracket for Shimano is designed specifically for frames using the T45 or ThreadFit82.5 standard, commonly found on Colnago models. It enables seamless installation of Shimano and other 24 mm spindle cranks, ensuring optimal compatibility and performance.

Precision-Built for Ultra-Low Friction: Each bottom bracket features CeramicSpeed’s hand-built bearings installed in precision-machined cups. The super round, ultra-smooth CeramicSpeed Balls rotate on hardened-steel races, dramatically reducing friction and improving the bike’s overall power transfer efficiency.

Standard and Coated Bearing Options: The T45 bottom bracket is available with either Standard or Coated Bearings. The Coated option includes a 3-micron metallic layer applied to the races, making them even harder and smoother. This reduces drag further while extending bearing life under intensive riding conditions.

Durability and Performance in All Conditions: Engineered for maximum longevity, the T45 system resists contamination and corrosion, maintaining smooth rotation even in wet and gritty environments. Riders benefit from improved responsiveness and sustained drivetrain efficiency mile after mile.

With industry-leading low friction, optimized power transfer and exceptional durability, the CeramicSpeed T45 Bottom Bracket elevates performance on any Colnago equipped with T45.
