Acros ZS56 Headset Upper for Integrated Cable Routing

Hardly any other component is more hidden but nevertheless important than the Headset. More than 15 years of know-how in bearing technology are directly reflected in our products. The result are high-end headsets with the right spark of glamour and elegance.

The combination of stainless steel angular contact ball bearings and sophisticated sealings ensure durability with minimal maintenance and therefore more worry-free time in the saddle.

A semi-integrated headset (zs) for frames with 56mm head tube at the top and integrated cable routing (icr). It can only be used in combination with matching headset cover (zs 56 headset cover) for integrated cable routing. The headset-upper-part includes a zs56 bearing cup, a matching angular contact ball bearing, a special compression ring for icr and internal protection sealing (ips) as an additional protection of the headset bearings against moisture and dirt.
