The ISO AB is specifically for “Boost” disc spacing forks with 110x15mm "Boost" axles. Using the larger diameter hubshell bearing the ISO AB is designed to tackle rough terrain and aggressive riding such as downhill and enduro.
With the ISO AB hub your wheel will be future proof and ready to convert to the new 110x20mm axle with a simple insert swap, should that spec expand beyond downhill forks in the coming years.
Chris King ISO AB front hubs are designed as precision mountain tools. Using 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.
Chris King bearings, available in steel and ceramic, have heat-treated, surgical grade steel races that are machined simultaneously, with tools of equal wear to ensure perfectly matched inner and outer races. The quality and speed of King bearings is what sets them apart from the competition and they are what you will feel and notice on every single ride. As Chris King bearing tracks burnish they get faster with age and all their hubs and bearings are fully serviceable for years upon years of demanding use.
