Aheadset Zero Stack Headset

AheadSet was spawned with one goal in mind; minimize the number of unique parts in order to maximize interchangeability among headset configurations. To accomplish this, AheadSet created a certain commonality amongst parts, making the AheadSet system adaptable to a number of unique headset configurations. From traditional models to ZeroStack for threaded or threadless 1" or 1 1/8" models, the AheadSet system features 21 unique parts that enable 11 unique headset arrangements to solve almost all fitting issues.

AheadSet ZeroStack Headset

The AheadSet ZeroStack (ZS) headset design brilliantly uses the same part for the cone and crown race, offering simplified installation and less unique parts. The way it works is that the cone design allows it to be used as a crown race when flipped over, creating mirrored top and bottom cup assemblies. Similarly, the compression ring is incorporated into the top cover creating one simple, lightweight part that serves as both. To provide fortification from contaminates and increase the ZS’s life expectancy, the cups and cones work together with an innovative LubeAlarm o-ring that audibly alerts the rider when more grease is needed.
