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!
