ACROS Headset Upper Part - 1 1/8 Inches - ZS56/28.6 - OD62 - black

Headsets are inconspicuous, but indispensable. Above all, a headset is more complex than it appears at first glance. Acros has spent years tinkering with and thinking about the ZS56 headset so that you never have to do that: you can simply install it and have your peace of mind for a long time.

This is made possible by a double-sealed stainless steel angular contact ball bearing, which Acros fill with their optimized headset grease. The two sealing discs with double lip seals keep the grease safely inside the industrial ball bearing and prevent moisture and dirt from entering the bearing. So Acros offer you a long lasting function, no matter what happens.

The ZS56 upper part is completed with further seals that prevent dirt and water from even reaching the headset bearing. This ensures long life with minimal maintenance - so you can maximize your time behind the handlebars and enjoy it to the full.

The S.H.I.S. denotation (see attachment) for the upper part offered here is ZS56/28.6 (with the 1 1/8" crown race) with 62mm outer diameter (OD).
