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

The Y1Rs reduces frontal area by 19% compared to the V4Rs, thanks to innovations such as the CC.Y1 handlebar with WYND© technology and the curved down tube. These elements reduce air resistance and optimize aerodynamic flows in every wind condition.

The frame structure is designed for a 3.5% higher stiffness compared to the previous model. This ensures immediate power transfer during the most intense sprints and unmatched responsiveness.

The handlebar features a "seagull wing" shape design that reduces airflow separation and improves stability at high speeds. All this without compromising stiffness, making it ideal for the most powerful riders.

The Y-shaped double junction improves aerodynamics around the seatpost area and better absorbs vibrations, increasing comfort without sacrificing stiffness. Perfect for long breakaways and endurance stages.

Tests conducted in real configurations show that the Y1Rs requires 20 watts less than the V4Rs to maintain a speed of 50 km/h. A significant advantage in fast races and windy courses.

The Y1Rs is compatible with the most advanced electronic groups and offers a fully integrated design, from custom bottle cages to an aerodynamic seatpost. Every detail has been optimized to reduce weight and enhance aesthetics.
