CeramicSpeed BB90 Bottom Bracket Trek SRAM GXP

The CeramicSpeed BB90 Bottom Bracket for Trek SRAM GXP is engineered for riders seeking the lowest friction and optimal power transfer. Designed specifically for Trek’s BB90 standard, it maximises efficiency while delivering exceptional durability and resistance to contamination.

Purpose-Built for Trek’s Unique BB90 Standard: Trek created the BB90 platform to optimise stiffness and frame integration. With a 90.5 mm shell width and 37 mm inner diameter, the bearings sit directly inside the frame, eliminating the need for traditional external cups and ensuring a clean, highly efficient interface.

Premium CeramicSpeed Bearing Options: The kit includes two bearings that press directly into the frame, available in Standard or Coated versions. Both options use ultra-smooth CeramicSpeed balls matched to hardened-steel races, providing extremely low friction and excellent power transfer during every ride.

Enhanced Durability With Coated Bearings: The Coated variant adds a thin metallic layer to the raceways, making them even harder and smoother. This improves resistance to wear, reduces drag and significantly extends bearing lifetime—ideal for riders who demand ultimate performance and longevity.

With industry-leading smoothness, long-lasting construction and compatibility with SRAM and Quarq 24/22 mm spindles, the BB90 Trek SRAM GXP bottom bracket is built to deliver fast, reliable performance in all riding conditions.
