CeramicSpeed BB90 Bottom Bracket for Trek Shimano

The CeramicSpeed BB90 Bottom Bracket for Trek Shimano is engineered specifically for Trek road bikes using the BB90 standard. With a 90.5 mm shell width and internal bearing placement, it pairs seamlessly with 24 mm Shimano road crank spindles for a precise and efficient fit.

High-Quality Bearings for Smooth, Stable Rotation: This system includes two CeramicSpeed bearings that press directly into the frame, eliminating the need for external cups. Each bearing is crafted to deliver exceptionally smooth rotation, improving pedaling efficiency and reducing energy loss during high-intensity efforts.

Choose Between Standard and Coated Bearings: Riders can select either the Standard or Coated bearing versions. Both use super round CeramicSpeed balls running in hardened-steel races, while the Coated option features an additional metallic layer that increases hardness, reduces drag and further extends bearing life.

Optimized for Speed, Power and Longevity: With ultra-low friction, improved power transfer and industry-leading resistance to contamination, the BB90 system enhances performance over thousands of kilometres. The integrated design also increases frame stiffness and pedaling responsiveness.

Purpose-built for Trek’s BB90 platform, this bottom bracket offers long-lasting durability, smoother rotation and superior efficiency for demanding road cyclists.
