As rim technology progresses, riders are using more aerodynamic rims in training, centuries, road races, criteriums and all events in between. This is now possible because these new carbon rims are so light. And, Enve pushes this aero/lightness ratio even further with their Carbon Tubular Rims. Their unique carbon fabrication method results in the ideal balance of stiffness, aerodynamics and weight. These rims also boast specially tuned sidewalls that dissipates heat from braking so you can descend as fast as you dare.
