Chris King ISO AB Disc 6-hole Boost hub front 110x20mm

In a nutshell, our fat tire friends deserve the same dazzling perfection from their hubs as everyone else. Everyone wants dazzling perfection, right? Using a larger diameter hubshell bearing the ISO AB is designed to tackle rough terrain and aggressive riding such as downhill and enduro.

Aggressive trail riding screams out for high-performance equipment. When every decision you make needs to turn into action in the blink of an eye, you want a hub that is just about telepathic. We use one-piece axles to provide a stiff hub with rail-accurate steering, transferring every minute adjustment you make to the trail. To thwart mud, water, and contaminants as you power through rough trails, ISO hubs have heavy-duty bearing seals and snaprings that provide superior protection with ultra low drag.
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 get actually get faster. A little bit of regular love (i.e. service) will keep this hub rolling for years upon years of demanding use. The ISO AB is specifically for “Boost” disc spacing forks with 110x20mm "Boost" axles.
