Box One X5 Pro Carbon Forks



SKU: 1181-6 Category:

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 pushes our Oversized Technology to the extreme as it includes the 1.5 to 1-1/8 inch tapered 7000 series aluminum steerer tube and stiffer 20mm through-axle cold-forged dropouts. Say good-bye to deflection.

Weight Limit: 115kg (253 lbs) with limitations as per Category 2 of EN 16054:2012 Standard
