Chris King hubs are known for innovative bearing and gearbox designs, exceptional durability, and for their brilliant jewel quality anodized colors and finishes.  King Boost Centerlock rear hubs use one-piece solid axles to provide a stiff platform that makes your suspension perform better.

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. King bearings, both steel and ceramic, have heat-treated, surgical grade steel races that are machined simultaneously to ensure perfect matching.  As Chris King bearing tracks burnish they get actually get faster. A little bit of regular love (i.e. service) will keep this hub rolling for years upon years of demanding use. 

Rear hubs employ King patented RingDrive gearboxes with 72 points of simultaneous engagement to get power to the ground quickly.  The RingDrive system is easily identified by its trademark “Angry Bee” sound.

Hubs are fully serviceable for many years of demanding use. All Chris King products are 100% engineered, manufactured and assembled in Portland Oregon and carry a limited lifetime warranty.

IMPORTANT NOTE: King MTB hubs currently have a 14 day lead time for items not in stock.
