There is more to our carbon headsets than their striking good looks. From top to bottom, Box One™ Carbon Headsets was designed to perform. Each unit features a custom CNC-machined aluminum compression cap in the shape of the Box logo with cut-outs to reduce weight. At the center of the compression cap is an anodized aluminum bolt that threads into a gold anodized aluminum expander plug. This expander eliminates the need for a star nut and works with all 1-1/8-inch steerer tubes—even carbon fiber steerer tubes. The bearing cover is crafted from carbon fiber, which not only adds style but helps shave weight. At the heart of the headset are two super-smooth, titanium-nitride coated, sealed, 45×45 bearings. The titanium coating results in a low friction coefficient, increased corrosion resistance, and smoother rolling bearings. A split crown race makes installation and removal from forks super easy.

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 onto 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. FEATURES - Oversized Technology™ - Massive 1.5” Diameter - Massive Sealed Bearings - Star-Nut Compression System - Includes 1-?” Reducer Race for 1-1/8” Steerer Tube COMPATIBILITY - Box One X5 Fork - Box One X2 Fork - Box One XL Fork - Frames with an Integrated NON-Tapered Head Tube
