When we set out to design our R45 hub we had over 30 years of bearing experience and 20 years of building hubs under our belts. The R45 is the culmination of that experience; we focused on creating a lightweight road racing hub that utilized hallmarks of Chris King components: precision, performance, and quality. Our R45 rear hub combines a redesigned RingDrive system with 45 teeth for lower drag and near instant engagement with a lightweight hub body and our legendary made-in-house bearings. 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. The patented Chris King RingDrive with 45-points of simultaneous-engagement will get your power to the ground fast, provide unmatched engagement, and give you that legendary Chris King angry-bee sound. - Engineered, manufactured and assembled in Portland, Oregon USA - 5-year built-to-last warranty - Legendary made-in-house bearings - Easily serviceable and completely re-buildable with our R45 Hub Service Tool
