Chris King Hub Front Boost 6-bolt Ceramic

The Boost 6-Bolt front hub is designed specifically for forks with the "Boost" brake disc standard and 110 x 15 mm "Boost" axles. Thanks to its larger hub bearings, the Boost 6-Bolt is built for rough terrain and hard riding – from enduro to downhill. In a market full of changing axle standards, we're confident: the "Boost" brake disc position is here to stay.

Chris King Boost 6-Bolt front hubs are engineered as precision tools for serious mountain biking. We use one-piece axles to deliver maximum stiffness and rail-like steering – every tiny handlebar adjustment is transmitted directly to the trail. To keep mud, water, and dirt at bay, the Boost hubs are equipped with heavy-duty bearing seals and circlips that provide superior protection with extremely low rolling resistance.

Our bearings, available in steel or ceramic, run on heat-treated, surgical-grade precision raceways. Inner and outer rings are simultaneously worn with uniformly sized components.
