Aheadset ZS Zero Stack Headset



The ingenious design of the Aheadset ZS Zero Stack Headset. The cone allows it to be used as a crown race when turned over. This means the cup, bearing, and cone form identical top and bottom assemblies promoting easy installation and fewer unique parts. The cups and cones work together with an innovative LubeAlarm o-ring to seal-out contaminants. The compression ring is integrated into a first of its kind compression cover creating a simple and light assembly. The Aheadset ZS Zero Stack Headset features ball bearings.
