The semi-integrated headset AZX203 1 1/8"-1.5" ZS44/28.6|ZS56/40 from Acros with 9 mm high aluminum cap enables the installation of 1 1/8"-1.5" tapered forks in frames with 44 mm / 55 mm press-fit dimension. The bearing set consists of a stainless steel angular contact ball bearing with a vulcanized seal for optimum protection of the headset bearing against moisture and dirt. Zerostack (ZS) designs are extremely popular as they combine the advantages of low overall height and bearing shells.

High-quality ball bearings for your bike: ACROS AZX203 1 1/8"-1.5" ZS44/28.6|ZS56/40 headset

As a subsidiary of a renowned bearing manufacturer, Acros was born with a passion for bearings. That's why Acros develops headsets and bottom brackets for a carefree time on the bike. The mission is simple: ride more, worry less - regardless of the weather and whether you're on the mountain passes, gravel roads or trails of this world.

Headsets are inconspicuous, but indispensable. Above all, however, a headset is more complex than it seems at first glance. The two sealing washers with double lip seal keep the grease securely inside the industrial ball bearing and prevent moisture and dirt from penetrating the bearing. Acros thus offers you long-lasting function, no matter what.
