The revolutionary Vigor wheel was the one to start it all. An aerodynamic wheel that rivals the weight of climbing category wheels, the Vigor wheel is light, stiff and extremely fast. Ideal for fast rides over flat to rolling terrain but a great wheel for climbing too. Proven time and time again in time trials, triathlons, road races and crits, the Vigor's combination of light weight, stiffness and extreme speed make it the best all around wheel available.
