ACROS Headset Blocklock Lower Part | 120° | Polygon | ZS56/40 1 1/2"
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 lower blocklock headset, you protect your frame from unpleasant contact with the handlebars, add-on parts or the triple clamp. The cables are also not overstressed. The steering stop is still 120°, which is perfectly adequate for most steering commands and riding maneuvers, but you will have to do without the barspin.
As is typical for Acros, a high-quality double-sealed stainless steel angular contact ball bearing filled with optimized headset grease is also used in this lower part of the headset. The two sealing washers with double lip seal keep the grease securely inside the bearing and protect it from moisture and dirt ingress. It is a ZS version (Zero Stack - semi-integrated) with a press-fit dimension Ø of 56 mm. The bearing is completed with a special blocklock fork cone. This guarantees a long service life despite minimal maintenance.
Note: Please check the clearance of your frame. You will need the following tools for assembly:
Acros DIY press-in tool for headsets
Acros impact tool fork cone
Acros impact tool fork cone adapter 1.5"
