The wins keep piling up for the fastest UCI-legal bike in the world. Professional road races, Ironman triathlons and amateur events worldwide. Developed in the wind tunnel, the DA’s radically-shaped UHC-Nano carbon fiber frame and Bayonet 2 Steering System help it cheat the wind like no other bike on the market. And now the DA is available with one more competitive advantage—the incredibly advanced Shimano Di2 electronic shifting. Aerodynamics, efficiency and touch-button controls—the future has arrived.
