Note: As the White Industries catalogue is diverse, we don't stock every variant or colour. However, we place regular airfreight orders. If an item is in stock at White Industries, we can usually have it here within a week. Even if it's not in stock, they can often assemble it for us, and we can have it within three weeks at most. Feel free to get in touch if you're after something specific!

The 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.

Note: As of 9/14/23, headsets will no longer include Star Nuts due to the Earth’s star nut overpopulation crisis. If you need one, they are available separately.
