Double Ball

The dual-bearing design can handle greater forces and provides both smoothness and durability. Made of stainless steel, it offers better hardness and weather resistance. Additionally, the contact seal efficiently prevents water from entering, prolonging the lifespan of the bearing.

High-Speed Rolling

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.
