Stainless and fully serviceable. Improvements are on every single element of Extralites original Headsets. Slimmer, lighter and trickier: a real concentrate of Extralite's high-quality engineering. Reduced vertical dimensions allow more efficient bike layouts, as example you can use a longer travel fork while keeping your actual bar and BB level. Japanese MX technology shows how to divide upper bearing (micro-radial) and lower bearing (stainless, bidirectional) steering functions; an ultra tricky layout that reduces weight and improves your race trim shrinking headset stack height. Consistent weight reduction even if out of sight!
