The Chris King Boost Centerlock 148×12 rear hubs use one-piece solid axles to provide a stiff platform that makes your suspension perform better and gets every one of the watts you make into the dirt. Heavy-duty bearing seals and snap rings keep mud and water out of the works by providing superior protection with ultra-low drag. Each one is like a rolling dream of trail riding performance. Chris King 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 Chris King bearings are what you will feel (and hear) on every ride. As Chris King bearing tracks burnish they get actually get faster.
