Description
The Colnago Y1Rs Dura-Ace Di2 Road Bike is engineered to defy the wind, delivering exceptional aerodynamic efficiency and performance for sprinters and breakaway specialists. This cutting-edge bike combines advanced technologies with innovative design, ensuring peak efficiency, control, and comfort.
Designed with a reduced frontal area that is 19% smaller than its predecessor, the Y1Rs incorporates features such as the CC.Y1 handlebars with WYND technology and a curved downtube to optimise airflow in all wind conditions. These aerodynamic improvements, combined with a 3.5% increase in frame stiffness, deliver immediate power transfer for intense sprints while maintaining exceptional responsiveness.
Every detail of the Y1Rs has been refined and validated in real-world racing scenarios, ensuring unparalleled performance and aesthetic appeal.
