Chris King hubs are known for innovative bearing and gearbox designs, exceptional durability, and for their brilliant jewel quality anodized colors and finishes. 

The R45 line evolved from the battle-tested classic MTB hubs, with the goal of creating a lightweight road worthy design.  King hubs control flex by adopting an oversize axle diameter made possible with the use of proprietary bearings. 

Rear R45 hubs employ King patented RingDrive gearboxes with 45 points of simultaneous engagement to get power to the ground quickly.  The R45 RingDrive system is significantly quieter than the classic 72 point version identified by its trademark “Angry Bee” sound.

Bearings are available in steel and ceramic for most models. Races are manufactured from heat-treated, surgical grade steel that are machined simultaneously, with tools of equal wear to ensure perfectly matched inner and outer races. As Chris King bearing races burnish they get faster with age. 

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 5 year warranty.
