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.

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.
