Why We Make This

It’s our job to make the best riding hubs in the industry, and 142mm x 12mm rear hubs are THE standard for road disc and gravel bikes, so we poured our hearts and souls, not to mention an awful lot of engineering, into this hub. We think it’s the best all-around disc hub on the market.

Why You Want It

R45 Centerlock™ hubs combine a lightweight hub body, our legendary made-in-house bearings, and Centerlock compatibility. The result rolls better, lasts longer, sounds cooler, and looks way more handsome than anything else out there.

On top of all that, the 45 points of simultaneous engagement in this hub improve power transfer and traction thanks to our patented RingDrive™ system.

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 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.
