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.
About the Vision brand
Since its birth in the ‘90’s, Vision has been synonymous with a no-expense spared assault on wind resistance. Recent years saw the innovative application of carbon fiber and the creation of dream-like shapes to enhance performance. Perhaps no aerobar line has been so imitated, but usually with little success. Following yet another triumphant season in triathlon and TT, Vision is again the brand to beat. In Ironman competition, Vision has led the way by innovating slippery-fast aero products that actually function properly in race conditions. Aerodynamics combined with adjustability and fit take years to combine correctly. 2012 continues the quest for speed with the new Metron TFA aerobar. The TFA is UCI legal, exceptionally light, and rigorously tested with Computational Fluid Dynamics and wind tunnel testing. Along with the TFA, Vision continues to lead the industry with adjustment friendly semi-integrated, clip-on, and UCI legal bar options, as well as the revolutionary Metron groupset. Vision also becomes the driving force for new wheel technology in 2012 with a stunning range offering significant weight savings at price points not seen before. Visions' wheel assembly programme features both carbon and alloy rims with CNC hubs manufactured in-house by FSA's own purpose built wheel factories. The rims and hubs are combined with high precision SKF bearings and Sapim spokes to be hand built in Italy, the Artisan wheelbuilder adding a serial number to each wheel. FSA Italy and the new FSA UK Technical support centre offer advice, spares and support to keep your wheels rolling.
