Bottom Brackets
Screwing BB 24 Ultra
Tapered Profile
Fun 5° bearing technology not only enables automatic coaxialization for improved power output. Its easy maintenance feature ensures that it can operate smoothly for extended periods, while the angular contact bearing further enhances its reliability and longevity.
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.
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.
