This Ritchey WCS Carbon Headset Star Nut is no longer available although you may find similar or newer versions below:
A complete top cap assembly comprising of star nut, bolt, and with a carbon top cap for 1-1/8 inch diameter steerer tubes.
A bicycle headset attaches the fork to the frame, they consist of bearings and races which allow the forks steerer to move within the frames headtube. There are a few types of headset, these are threaded and ahead. Threaded headsets are the older type and use a thread on the forks steerer to adjust, an ahead type has no thread and uses a top cap to adjust the tension. Ahead headsets come in three options, external cup, internal and integrated. Integrated and internal headsets use bearings which fit inside the headtube and provide clean lines, whereas the external cup system uses cups which fit into the frame but are still visible. Most will use cartridge bearings which last well and have very low maintenance requirements, one thing worth doing is to switch the top and bottom bearing periodically, as the bottom bearings are more prone to wear as they support the weight of the bike and rider.
Ritchey is well known for ingenious mountain bikes and parts, but Tom Ritchey was building world class road frames and rethinking every part of the road bike as early as 1974---long before mountain biking came along. After decades of refinement, Ritchey road components are the lightest, strongest and highest quality parts available, and race proven by top professional teams in the world's toughest pro races. Look for Ritchey components on team bikes in the Tour de France, Giro d'Italia, World Championships and Spring Classics, as well as countless other races.
