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│EC44 headset is designed to fit frames with straight 44mm head tubes and can accommodate straight and tapered fork steerers with the appropriate crown race. The “ZS” stands for “Zero Stack” as the section of the cup that houses the top bearing sits inside of the frame’s head tube while “EC” stands for “External Cup” meaning the section of the cup that houses the lower bearing sits outside of the frame’s head tube. The “44” stands for the 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.
