Small but Powerful

Crafted exclusively for Trek BB90/95 frames, this bottom bracket boasts an angular contact design that maximises power transfer for enhanced durability and faster speeds. Featuring highly effective contact seals, it provides exceptional water resistance, making it incredibly long-lasting.

Ceramic Rolling

This technology incorporates ceramic beads with low resistance that are immune to rust, deformation, and bonded with nano grease. These features provide the benefits of reduced resistance, faster running speeds, and exceptional water resistance, surpassing the performance of conventional steel balls.
