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 also takes our application of Oversized Technology one step further as it includes a tougher 1-1/8 inch chromoly steerer tube and stiffer 20mm through-axle cold-forged dropouts.


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

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).

Light and strong. Great fit and finish (I bought the gloss black to compliment my gloss blue HARO Race Lite frame). A huge upgrade over the stock chromoly fork. A very stiff and confident fork for larger riders and heavy hitters.

Love these!

These forks are amazing, it really transformed the bike and improved the overall feel significantly. Light, stiff and looks so good. The matte finish was better looking than I was expecting!

These are the best forks

I was nervous getting the step down from the X5 series of forks but was incredibly impressed with their strength and rigidity in the gate and on the straight giving me the most responsive Control of my bike
