All Box One forks are engineered and crafted using our Oversized Technology. These forks are the single most crucial component in the quest for bike control. We’ve moved carbon from areas of low stress to areas that handle high load. Those muscular shoulders aren’t just for looks, as they are integral to achieving superior steering stiffness. When combined with Box’s other Oversized components, you’ll experience heightened responsiveness and reduced latency.

Key differences: This particular model fork is tailored for smaller racers and includes a lighter weight 1 inch 7000 series aluminum steerer tube and 10mm cold-forged dropouts.
