TSRf allows cyclist to commit undivided attention to training and racing, and winning. 

Wind tunnel testing confirmed that a combination of the bullet shapes ability to slip through wind and the Kamm tail shapes ability to streamline airflow results in an optimal tube design for high speed TT races. 

To Balance hydromechanics and air turbulent flow for forward motion, DARE has developed a way to provide down force for positive airflow. The upper edge of the front fork crown is aligned with the rear stay wind breaking wing in design. The airflow passes through the front fork crown to the rear stay that generates down force to improve stability of the rear triangle, enhancing pedaling revolution efficiency. 

Note; bike is delivered with Ultegra group set, not with Dura-Ace as shown in the picture.
