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.

The IS41│IS41 headset is designed to fit frames with integrated 41mm head tubes and works with straight 1-⅛” (28.6mm) fork steerers. The “IS” stands for “Integrated” as the bearing sits directly inside the frame’s head tube without a cup. The “41/41” stands for the top/bottom inside diameter of the frame’s head tube. 

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.
