Key Benefits
* Seamless 12-Speed Integration: Featuring the innovative MicroSpline freehub body, this hub is exclusively designed for SHIMANO 12-speed cassettes. This allows for the use of a wide-range cassette with a 10T small cog, providing an exceptional gear range for tackling both steep climbs and fast descents with unparalleled efficiency.
* Enhanced Wheel Stiffness and Control: The “B” designation signifies its Boost 148x12mm spacing. This wider flange placement increases the bracing angle of the spokes, resulting in a significantly stiffer and stronger wheel. This translates directly to more precise handling, improved stability, and greater confidence when navigating challenging terrain.
* Effortless and Secure Brake Rotor Installation: Equipped with Shimano´s Center Lock system, mounting a disc brake rotor is faster and easier than ever. The spline mount and lock ring design ensures a secure, wobble-free connection for consistent and powerful braking performance, while simplifying maintenance and installation.
* Legendary Durability and Serviceability: The hub utilizes Shimano´s proven cup & cone bearing system. This design is more effective at handling angular loads than sealed cartridge bearings, offering superior durability and a longer lifespan. Furthermore, they are fully adjustable and serviceable, allowing for easy maintenance to keep your hub rolling smoothly for years.
