Semi-integrated headset (zs) with steering stop. Suitable for bikes with a 56mm head tube at the bottom. Our blocklock zs56 headset ensures that your top tube and down tube are protected from contact with the handlebars, attachments and the fork bridge and that the lines and cables are not overstressed in the event of a fall. For forks with a 1.5" steerer tube (40mm) at the bottom. ATTENTION: The 150° variant is not approved by every frame manufacturer. Using a larger steering stop can cause damage!


  • Copmpatible with Propain TYEE 6 CF / AL
  • double sealed angular contact ball bearing
  • Stainless steel ball bearings


Headsets are inconspicuous but indispensable. Above all, a headset is more complex than it seems at first glance. We spent a long time tinkering and thinking about our zs56 blocklock headset so that you never have to: you can simply install it and have peace of mind for a long time. This is ensured by a double-sealed angular contact ball bearing made of stainless steel, which we fill with our optimized headset grease. The two sealing discs with double lip seals keep the grease safely inside the industrial ball bearing and moisture and dirt cannot penetrate the bearing. This way we offer you long-lasting functionality, no matter what happens. The blocklock function also ensures that you don't have to worry about your top tube. It is safely protected from contact with the handlebars and attachments and the lines and cables cannot be overstressed in the event of a fall. You still have 120° of steering angle available. This means you don't have to do barspins, but you still have more than enough freedom for radical driving maneuvers!
