All Box headsets are engineered and crafted using Oversized Technology. Since any steering stiffness can easily be lost to headset play, Box concentrated their attention on manufacturing tolerances and quality of materials for the bearing, cnc bearing cover, and crown race. 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.
