Simplification and challenges

The 20T internal locking mechanism is not only designed to increase installation fault tolerance while maintaining an aesthetically pleasing appearance. It also features a centre tube that prevents foreign object intrusion, making it weather-resistant and capable of overcoming a wide range of challenges.

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.

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.
