Why We Make This It’s our job to make the best riding hubs in the industry, and 100mm x 12mm front 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’re proud of it. Why You Want It We already said it was the best, but everybody says that. Our R45 Centerlock™ hubs pair a lightweight hub body with our legendary, made-in-house bearings. The result rolls better, lasts longer, and looks way more handsome than anything else out there. The stiffness of our one-piece axle translates to laser-precise bike handling. This hub also comes in one million (actually a handful) of cool colors. 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.
