Race Face Vault Rear hub, 12×157 XD (Superboost), Black

The Vault hub offers ultra-fast engagement, now available for your custom wheel builds. With both Boost and non-Boost options, a range of axle standards, and compatibility with Shimano or XD cassette bodies, it’s perfect for mountain bikers and e-bike enthusiasts alike. Its oversized hub shell boosts torsional and lateral stiffness, while the high-quality 6902 bearings, known for their durability and large ball diameter, ensure long-lasting performance.
This hub features a 60-tooth drive ring that alternately engages six double-tooth pawls, providing a quick 3° engagement for almost instant power transfer. The strategically placed wide bearings reduce load, enhancing bearing lifespan. Additionally, low-drag labyrinth seals protect the internal components, minimizing friction and ensuring smooth performance.
