All Box headsets are engineered and crafted using our Oversized Technology. As we follow the load paths down the handlebars, through the stem-to-bar interface, we arrive at the headset focal point. Since any steering stiffness can easily be lost to headset play, we have concentrated our attention on manufacturing tolerances and quality of materials for the bearing, cnc bearing cover, and crown race. Now that this junction is steadfast you can rest assured that your cockpit’s steering stiffness will transfer on to the fork. When combined with Box’s other Oversized components, you’ll experience heightened responsiveness and reduced latency.

Key differences: In this particular model headset we’ve gone to a 1.5” bottom race to fill a tapered head tube. This mates with our oversized X5 carbon fork. Larger and smoother contact areas spread the load effectively and counteract flex.

    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 we 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 our 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 our Oversized technology. By adding size to specific areas of components we have not only increased pedaling and steering stiffness, we 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.

    We don’t just manufacture carbon fiber parts. We 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 we don’t just buy “aerospace grade alloys” we choose the appropriate aluminum alloy for the component, and send it through the appropriate heat treatment processes. We demand material certifications as part of our quality assurance program.
