In an evolving landscape of axle specifications, we are confident that the “Boost” disc location is here to stay.

Chris King Boost 6-Bolt front hubs are designed as precision mountain tools. We use one-piece axles to provide a stiff hub with rail accurate steering, transferring every minute adjustment you make to the trail.
