Chris King hubs are known for innovative bearing and gearbox designs, exceptional durability, and for their brilliant jewel quality anodized colors and finishes. 

The ISO AB is specifically for “Boost” disc spacing forks with 110x15mm "Boost" or 110x20mm "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.

The ISO AB front hub is also compatible with Torque caps in the 110x15mm Boost configuration. 

Bearings are available in steel and ceramic for most models. Races are manufactured from heat-treated, surgical grade steel that are machined simultaneously, with tools of equal wear to ensure perfectly matched inner and outer races. As Chris King bearing races burnish they get faster with age. 

Hubs are fully serviceable for many years of demanding use. All Chris King products are 100% engineered, manufactured and assembled in Portland Oregon and carry a 5 year warranty.
