Acros IS52/30 headset lower part

Steering rates may seem inconspicuous, but they are indispensable. In fact, a steering rate is more complex than it appears at first glance. Acros has spent years refining and contemplating the IS52 steering rate so that you never have to: you can simply install it and enjoy long-lasting peace of mind. This is ensured by a double-sealed angular contact ball bearing made of stainless steel, filled with optimized steering bearing grease by Acros. The two sealing discs with double-lip seals securely keep the grease inside the industrial ball bearing, preventing moisture and dirt from entering the bearing. This way, Acros provides you with long-lasting functionality, no matter what comes your way. Our IS52 lower part is completed with additional seals that prevent dirt and water from reaching the steering bearing at all. This guarantees a long lifespan with minimal maintenance – allowing you to maximize and fully enjoy your time behind the handlebars.
