ACROS headset upper part | ZS49/28.6 1 1/8"
From the tranquil town of Renningen, in the green state of Baden Württemberg, straight to your bike! Behind Acros is a group of passionate cyclists and engineers. Their motto: ride more, worry less.
In typical Acros fashion, this headset upper part also uses a high-quality double-sealed stainless steel angular contact ball bearing, which is filled with optimized headset grease. The two sealing washers with double lip seal keep the grease safely inside the bearing and protect it from moisture and dirt. This is a ZS version (Zero Stack - semi-integrated) with a press-fit dimension Ø of 49 mm. The bearing is completed with an aluminum cover cap and matching Acros Ahead cap with claw.
