Bicycle Headsets
Traditional threaded headsets fit forks with threaded steerers. The adjustable race screws on to the steerer, and a locknut screws on after the adjustable race to secure it. Threaded headsets typically in use are 1" and are used on bikes with quill stems.
Threadless headsets have an adjustable race that slips over an un-threaded steerer. The most commonly used are the "Aheadset" style threadless headsets, which require a threaded fastener, such as a Star Nut to be installed inside the steerer.The most common size is 1 1/8".
