Spinning BB 30

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 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.

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.
