The patented Chris King RingDrive, with 72-points of simultaneous-engagement for Boost hubs, will get your power to the ground fast, provide unmatched engagement and give you that legendary Chris King angry-bee sound.

Chris King Boost 6-Bolt front hubs are designed as precision mountain tools. They use one-piece axles, providing a stiff hub for rail-accurate steering and improved suspension performance. To keep mud and water out of the works they have heavy-duty bearing seals and snaprings that provide superior protection with ultra-low drag. Each one is like a rolling dream of trail riding performance.

Our bearings, available in steel and ceramic, have heat-treated, surgical grade steel races that are machined simultaneously with tools of equal wear to ensure perfectly matched inner and outer races. The quality and speed of our bearings is what sets us apart from the competition and they are what you will feel and notice on every single ride. As Chris King bearing tracks burnish they get faster with age, and all our hubs and bearings are fully serviceable for years upon years of demanding use.
