When King set out to design their R45 hub they had over 30 years of bearing experience and 20 years of building hubs under our belts. The R45 is the culmination of that experience; they focused on creating a lightweight road racing hub that utilized hallmarks of Chris King components: precision, performance, and quality. The 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.
Their 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 their bearings is what sets them 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 their 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.
