Tapered Profile

Fun5 bearing technology not only enables automatic coaxialisation for improved power output. Its easy maintenance feature ensures that it can operate smoothly for extended periods, while angular contact further enhances its reliability and longevity.

The Art of Stability

The 20T internal locking mechanism not only has greater installation fault tolerance while maintaining a sleek appearance, but also features a Thread Together structure that prevents foreign objects from entering. This increases rigidity, enabling it to conquer more challenging terrains. This innovative design provides cyclists with greater confidence and control during rides, making it an ideal choice for adventurous and rugged terrain.

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.
