Headsets

Why We Make This: The simple answer is that many contemporary bicycle frame designs call for the headset bearings to ride inside the frame’s headtube. After decades of making press-in bearing headsets, we needed to make headsets that worked in these newer frames. From the beginning we understood that integrated headsets posed a unique challenge in that the bearings are not pressed into a cup and sit loosely in the frame. When bearings are not pressed securely into a cup they shift and move, rapidly losing preload. As preload drops, the bearings are more susceptible to creaking, damage, and failure. That’s a problem we know how to solve. Why You Want It: Enter, our patented GripLock™ bearing cap. The GripLock™ preloads the headset independently of clamping onto the steerer, so it retains preload far better than the competition and is impervious to the ill effects of load spikes from large hits and heavy braking. This means smoother steering, no more creaking, and a longer lasting headset. Our GripLock™ design also takes the guesswork out of preloading a headset, because the bearing preload force is independent of the clamping force. Our headsets can be preloaded to a torque spec.

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

The GeoShift Performance Angle Headset allows you to adjust the geometry of your bike by changing the head tube angle, available in 1 or 2 degree options. This unique design lets the bearings sit at an angle to align with the steerer tube, preventing creaking noises commonly found with angle headsets that feature a spherical design. Reduce the head tube angle to make for slacker geometry and added stability on fast descents, or increase the angle using the opposite orientation of the headset, to make for steeper geometry and quicker steering with maximum front wheel traction. - Enduro black oxide coated chromium steel bearing included on both the upper and lower - Upper headsets ship with a star nut which can only be used on forks with steel or aluminum steerer tubes. For forks with carbon steerer tubes you will need a compression plug (sold separately) - Machined in the USA with lightweight, strong, durable aircraft-grade 6061 aluminum - Includes: Upper and lower cups, bearings, crown race, star nut, shims, stem cap with 5mm integrated spacer and bolt - 1 Degree Adjustment - Long version is designed for headtube lengths between 115 - 140 mm
