Colnago Y1Rs Disc Dura-Ace Di2 ENVE SES 4.5 with Power Meter

The Colnago Y1Rs represents the pinnacle of aerodynamic efficiency. This bike is designed to deliver optimal performance in high-speed races, combining advanced technologies and innovative design for sprinters and breakaway specialists.

With a design that drastically reduces air resistance, optimized stiffness for powerful sprints, and surprising comfort for long distances, the Y1Rs offers a perfect balance between performance, efficiency, and control.

Cutting-edge aerodynamics

The Y1Rs reduces frontal area by 19% compared to the V4Rs, thanks to innovations like the CC.Y1 handlebar with WYND© technology and the curved down tube. These features minimize air resistance and optimize airflow in all wind conditions.

Stiff where it matters

The frame is engineered to be 3.5% stiffer than the previous model, ensuring instant power transfer during intense sprints and unmatched responsiveness.

CC.Y1 handlebar with WYND technology

The handlebar has a "seagull wing" shape that reduces airflow separation and improves stability at high speeds, without compromising stiffness. Ideal for powerful riders.

DEFY seatpost junction

The double Y-joint enhances aerodynamics in the seatpost area and better absorbs vibrations, increasing comfort without sacrificing stiffness. Perfect for long breakaways and endurance stages.

Wind tunnel tested performance

Real-world configuration tests show the Y1Rs requires 20 watts less than the V4Rs to maintain 50 km/h. A significant advantage in fast races and windy courses.

Modern compatibility and integrated design

The Y1Rs is compatible with the latest electronic groups and features fully integrated design, from custom bottle cages to aerodynamic seatpost. Every detail is optimized to reduce weight and enhance aesthetics.
