ACROS is52 Headset Lower Part 1.5 Inches Drop In IS52/40

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 is52 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 is52 lower 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.
