Chris King MTB Boost Rear Hub | 6-Bolt | Steel Bearings

The MTB Boost 6-Bolt Rear Hub is wide, stiff and constructed with a solid, one-piece axle, making it perfect for standing up to the rigours of mountain biking and minimising the energy required to complete an intense route.

It is equipped with robust bearing seals and a sturdy, threaded driveshell seal ring, which keep mud, water and debris out of your components, minimising wear and corrosion and ensuring that the wheel will continue to roll fast and smoothly.

The hub's efficiency is further boosted by the inclusion of Chris King's meticulously designed bearings, machined simultaneously for perfectly matched inner and outer racings, which not only roll fast but burnish with age to be even faster.

Finally, it benefits from the patented RingDrive system, with its 72 simultaneous points of engagement. The generator of the coveted Chris King ‘angry-bee sound’, it maximises the engagement of the hub, ensuring that every bit of power you generate will make it to the ground.
