All Box One forks are engineered and crafted using our Oversized Technology. These forks are the single most important component in the quest for bike control. Weve moved carbon from areas of low stress to areas that handle high load. Those muscular shoulders arent just for looks as they are integral to achieving superior steering stiffness. When combined with Boxs other Oversized components, youll experience heightened responsiveness and reduced latency.Key differences: This particular model fork is tailored for larger-sized racers and also takes our application of Oversized Technology one step further as it includes a tougher 1-1/8 inch chromoly steerer tube and stiffer 20mm through-axle cold-forged dropouts.
