Chris King Boost 6-Bolt front hubs are precision tools built for mountain riding. Chris King use one-piece axles to create a stiff hub that provides ultra-precise, rail-like steering, translating every small input you make on the trail. To keep mud, water, and other contaminants out, the Boost hubs feature heavy-duty bearing seals and snaprings, offering superior protection with minimal drag.

Steel and ceramic bearings feature heat-treated, surgical-grade steel races that are machined simultaneously to ensure a perfect match. This attention to detail makes our bearings faster and more durable with age. They’ll make a difference you can feel on every ride.
