BOX BOX ONE X2 PRO CARBON FORKS

All Box One forks are engineered and crafted using our Oversized Technology. These forks are the most critical 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 larger-sized racers and takes our application of Oversized Technology one step further. It includes a tougher 1-1/8 inch Chromoly steerer tube and stiffer 20mm through-axle cold-forged dropouts.

FAQ
Are these forks compatible with OS 20 Wheels?

No. Due to the larger diameter of the wheel, these will not work. The largest compatible tire is 20 x 1.95.

May I use a star nut with this fork?
No. You must use the stem lock provided with the fork, or an equivalent expander plug (i.e. Box One Carbon Headset). Use of a star nut is prohibited and voids the warranty for this product.

Does this fork fit my frame?

To determine compatibility, first examine the head tube of your frame. X5 forks are only compatible with tapered head tubes (see below).
