The IS41/IS52 is White Industries tapered steerer headset for your 41/52mm head tube bike. When building this headset White Industries had three main focuses adaptability, durability and serviceable. With all the different head tube sizes and steerer sizes they made this headset adaptable by allowing you to use different crown races to fit your fork. Using 6061 aluminum for the cups, stainless steel bearings for durability, and integrated little details that make a big difference like a split crown race which enhances serviceability.  While headsets are not something you think about often it’s the little things, White Industries pride themselves in bringing you a rock solid product that you can trust.
