The White Industries IS41 | IS41 Threadless Headset delivers smooth steering, lasting durability, and timeless style for modern bicycles. We machine, polish, engrave, and inspect every headset in our Petaluma, California facility. As a result, the IS41 | IS41 offers the premium craftsmanship and dependable performance riders have trusted for decades.

For more than 30 years, White Industries has designed components that prioritize precision, reliability, and serviceability. The IS41 | IS41 Threadless Headset continues that tradition with premium materials, thoughtful engineering, and a clean, refined design built to last.

Every headset features premium Enduro stainless steel angular contact bearings for smooth, consistent steering in all riding conditions. These bearings are fully replaceable, making routine maintenance quick and easy while extending the life of your headset.

The IS41 | IS41 also features our split crown race design. It installs and removes by hand without specialized tools, making future service simple. In addition, every headset receives precision machine-engraved logos—not laser etched—for a premium finish that reflects the attention to detail found in every White Industries component.

The White Industries IS41 | IS41 Threadless Headset is designed for frames with integrated 41mm upper and lower head tubes. It is compatible with straight 1-1/8-inch (28.6mm) fork steerers, making it an excellent choice for many modern road, gravel, cyclocross, and commuter bikes. Because headset standards vary between manufacturers, we recommend confirming your bike’s SHIS (Standardized Headset Identification System) specifications before placing your order to ensure the correct fit.

Whether you’re replacing a worn headset or completing a custom bike build, the White Industries IS41 | IS41 Threadless Headset delivers smooth performance, premium craftsmanship, and American-made quality built to last.
