The headset that started it all, our 2Nut™ headset was designed in the late 70’s and quickly became the required headset for any serious rider. The 2Nut™ is built for use on bicycles with threaded forks that require the ability to use a steerer-tube-mounted cable hanger or additional spacers. Each 2Nut™ is constructed with our exclusive Chris King-made angular contact bearings for precision adjustment and smooth performance.
