The White Industries ZS44/ZS56 headset is designed to fit frames with tapered 44mm/56mm head tubes and works with tapered 1-1/2” fork steerers. The “ZS” stands for “Zero Stack” as the section of the cup that houses the bearing sits inside of the frame’s head tube. The “44/56” stands for the top/bottom diameter of the “skirt” that presses into the frame.
