The R45 front hub is lighter and more aerodynamic than most built-to-last hubs on the market. 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, both steel and ceramic, have heat-treated, surgical grade steel races that are machined simultaneously to ensure perfect matching. The quality and speed of our bearings is what you will feel (and hear) on every ride. 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.

All Chris King rear hubs come with that signature, angry-bee sound.
