Headsets are inconspicuous but indispensable. Above all, a headset is more complex than it might seem at first glance. We spent a long time developing and refining our zs56-blocklock headset so you never have to think about it: simply install it and enjoy lasting performance. This is ensured by a double-sealed stainless steel angular contact bearing, filled with our optimized headset grease. The two sealing washers with double-lip seals keep the grease safely inside the industrial bearing, preventing moisture and dirt from entering. This provides long-lasting functionality, no matter what conditions you face. The blocklock function adds even more protection: your top tube is safe from contact with the handlebar and components, and hoses and cables are protected from excessive stress in the event of a crash. You still have 120° of steering range available. While that means you can’t do barspins, you still have plenty of freedom for aggressive maneuvers! blocklock steering stop with 120° Double-sealed angular contact bearing Stainless steel bearing
