Product info
All Box One forks are engineered and crafted using 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. Weight Limit: 115kg (253 lbs) with limitations as per Category 2 of EN 16054:2012 Standard 7075-T6 Aluminum 1-⅛” Larger Diameter Steerer Tube to Accommodate Larger-Sized Racers Designed for 10mm Axle Conventional Hubs Internal Butterfly for Added Durability at Steerer Tube and Fork Crown Interface Legs: High Modulus Unidirectional Carbon Fiber Steerer: 7075-T6 Aluminum Butterfly & Dropouts: 6061-T6 Aluminum Legs: Vacuum Mold Steerer: Extruded & Butted Butterfly & Dropouts: Cold-Forged Hardware: Stem Lock Height: 24” Steerer: 1-1/8" Straight Offset: 32mm Dropouts: 10mm Height Axle to Crown: 354mm Weight: 575g / 20.3oz
