CHRIS KING HUBS

The patented Chris King RingDrive, with 72-points of simultaneous-engagement for Boost hubs and 45-points for the R45D, will get your power to the ground fast, provide unmatched engagement, and give you that legendary Chris King angry-bee sound.

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.

• Legendary made-in-house LD bearings


• Easily serviceable and completely re-buildable with our Chris King Hub Service Tool
