Box One Oversized X5 Pro Carbon Forks

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.

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

 

FEATURES:

  • Oversized Technology™
  • Tapered Steerer Tube to Reduce Deflection
  • 20mm Through Axle to Increase Responsiveness
  • Internal Butterfly for Added Durability at Steerer Tube and Fork Crown Interface

Includes Box One™ Stem Lock and Box One™ Fork Adapters.

Using a star nut voids the warranty for this product.
