Box One Oversized X2 Pro Carbon 2025 Fork

All Box One forks are engineered and crafted using Box's Oversized Technology. These forks are the single most important component in the quest for bike control. Box has 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 particular model fork is tailored for larger-sized racers and also takes Box Components's 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.

Technology

Oversized // Big = Fast

Oversized Technology is a philosophy of design and engineering. Its goal is to reduce energy oss to deformation or flex. The result are enchanced control, better acceleration, and increased speed.

Enhanced Power Delivery // Faster

There is no use pushing hard on your pedals if you can’t deliver most of that power to the rear wheel.

Power delivery AKA pedaling stiffness. When a rider pushes down on a pedal, the pedal, crank set, bottom bracket, frame and all the hardware holding those together deflects laterally. Stiffer components deflect less, so more of your energy output goes into turning the rear wheel, rather than deforming the components and frame. By using Oversized technology, Box is able to add only the appropriate amount of material for stiffness where it is most needed. It is possible to add too much stiffness where the rider will not feel the benefits. Going beyond that point simply adds material which is surplus weight.

Superior Control // Faster Response

Wonder why there is lag time between input from your hands to reaction from your bike?

Bike control can be defined as steering stiffness and this affects how your bike handles as a result of rider input. At Box Box Components define steering stiffness by how much the grips, handlebar, stem, fork, wheels, frame and all hardware between twists when they are ridden around a corner. Higher steering stiffness contributes to a more responsive handling bike by reducing latency between hand input and reaction in the bike. Just as with power delivery, by using Oversized technology, Box is able to add only the appropriate amount of material for steering stiffness where it is most needed. This allows Box Components's components to combat the cornering load as it passes along its load path from grip all the way through to contact point on the track.

Armored Build // More Durable

Why invest in cutting edge components if they don’t last?

Toughness is a natural byproduct of Box Components's Oversized technology. By adding size to specific areas of components Box Components have not only increased pedaling and steering stiffness, Box Components have also added toughness and strength. Larger surfaces also increase the ability of a component's ability to spread impact loads.

Advanced Materials // All Above

Not all things are equal when it comes to materials of construction.

Box Components don’t just manufacture carbon fiber parts. Box Components engineer where the strength/stiffness needs to be and the layer of fibers are added and aligned in the direction and angle required to provide the best effect. With metal alloys Box Components don’t just buy “aerospace grade alloys” Box Components choose the appropriate aluminium alloy for the component, and send it through the appropriate heat treatment processes. Box Components demand material certifications as part of Box Components's quality assurance program.
