This Vision Aero Time Trial Outer Chainring is no longer available although you may find similar or newer versions below:
130mm BCD Aero TT chainring made from 7075/T6 aluminium with 8mm lenticular disc shape making it stiff and aerodynamic.
Chainrings are fitted to the crank arms and come in single, double or triple configuration. Most geared bikes use a 3/32 inch width, whereas 1/8 inch is the popular choice for track bikes and some single speeds due to its increased strength which is needed when riding a fixed wheel. Chainrings are available in a number of formats, these are known as PCD's (Pitch Circle Diameter) or BCD's (Bolt Circle Diameter), this is the spacing of the bolts that secure the rings to the crank arms. Common sizes are 74mm inner ring Shimano MTB, 110mm middle and outer for Shimano MTB, 110mm for most compact chainsets to allow for the smaller ring combo's, 130mm for Standard Shimano Road and 135mm for Standard Campagnolo road chainsets.
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.
