Semi-integrated headset (ZS) for frames with 56 mm lower head tube. In the Acros ZS56 headset lower section, the combination of stainless steel angular contact ball bearings and sophisticated seals ensures a long service life with minimum maintenance and therefore more carefree time in the saddle.
Headsets are inconspicuous, but indispensable. Above all, a headset is more complex than it seems at first glance. Acros has spent years tinkering and thinking about the ZS56 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 is filled with headset grease optimised by Acros. The two sealing discs with double lip seal keep the grease securely inside the industrial ball bearing, preventing moisture and dirt from penetrating the bearing. This means that the Acros headset offers you long-lasting function, no matter what.
The ZS56 lower part is completed with additional seals that prevent dirt and water from reaching the headset bearing. This guarantees a long service life despite minimal maintenance - so that you can maximise your time behind the handlebars and enjoy it to the full. Zerostack designs are extremely popular, as they combine the advantages of low overall height and bearing shells.
