Why We Make This

Originally, we made this hub to be the cornerstone of our hub product line. We put all our hub and bearing experience into this product and ended up with a hub that struck that perfect balance between weight, performance, durability, and looks. Since the advent of disc brakes (and the R45D), we've kept making it because it’s still that cornerstone hub, and so many of our riders still love to rock their rim brakes on road and off.

Why You Want It

The R45 rear hub is lighter and more aerodynamic than most built-to-last hubs on the market. We use a narrow hub body and low flanges to make the R45 a rock-solid starting point for any fast wheel build.

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.
