ACROS headset Blocklock upper part | 164° | ZS44/28.6 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.
With this upper blocklock headset, you protect your frame from unpleasant contact with the handlebars, add-on parts or the fork bridge. The cables are also not overstressed. The steering stop is still 164°, which is perfectly adequate for most steering commands and riding maneuvers, you just have to do without the barspin.
As is typical of Acros, this headset top section 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 securely inside the bearing and protect it from moisture and dirt ingress. This is a ZS version (Zero Stack - semi-integrated) with a press-fit dimension Ø of 44 mm. The bearing is completed with an aluminum cover cap and matching Acros Ahead cap with claw.
Note: Please check the clearance of your frame and follow the attached PDF installation instructions. You will need the Acros DIY press-in tool for headsets.
