Acros IS52/40 headset lower part

Fully integrated headset for frames with a 52 mm lower bearing seat in the head tube. The combination of stainless steel angular contact bearings and well-designed seals in the lower part of the headset ensures durability with minimal maintenance, allowing for more carefree time in the saddle.

Headsets may be inconspicuous, but they are indispensable. In fact, a headset is more complex than it appears at first glance. Acros has spent years perfecting the headset so you don’t have to: you can simply install the headset and enjoy long-lasting peace of mind. This is ensured by a double-sealed angular contact bearing made of stainless steel, filled with Acros optimized headset grease. The two sealing washers with double-lip seals keep the grease securely inside the industrial bearing, preventing moisture and dirt from entering the bearing. This guarantees long-lasting functionality, no matter what comes your way. The lower part is completed with additional seals that prevent dirt and water from reaching the headset bearing. This ensures a long lifespan with minimal maintenance—so you can maximize and fully enjoy your time behind the handlebars.
