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. 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 therefore includes a lightweight 1-1/8 inch 7000 series aluminum steerer tube and 10mm cold-forged dropouts.

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