Carbon fiber is exceptionally light, stiff, and strong. A carbon wheel is often much lighter and stiffer than a comparable aluminum wheel. The low weight and increased stiffness will improve your bike's acceleration and handling. This makes carbon the most popular option for racers or anyone who cares about performance.
Because of carbon's high strength-to-weight ration, carbon wheels can also be made deeper and wider without a major weight penalty, improving aerodynamic efficiency, handling, comfort, and rolling resistance.
