Features

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.

High-Speed Rolling

By integrating high sphericity steel balls and nano grease, this technology significantly reduces friction and enables high-speed operation, while maintaining exceptional waterproof capabilities. Cyclists can now enjoy a tight and efficient riding experience, regardless of the weather conditions, and achieve better performance and control on a wide variety of terrains.

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.
