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.
