Colnago Y1Rs Ultegra Di2 Vision Road Bike

With a design that drastically reduces air resistance, stiffness optimised for the most powerful sprints, and surprising comfort for long distances, the Y1Rs offer the perfect balance of performance, efficiency, and control.

Cutting-Edge Aerodynamics
The Y1Rs reduces its frontal area by 19% compared to the V4Rs, thanks to innovations like the CC.Y1 handlebars with WYND© technology and the curved downtube. These elements reduce drag and optimize airflow in all wind conditions.
Stiff Where It Matters
The frame structure is designed to provide 3.5% greater stiffness than the previous model. This ensures immediate power transfer during the most intense sprints and unparalleled responsiveness.
CC.Y1 Handlebars with WYND© Technology
The handlebars feature a "gull-wing" design that minimises airflow separation and improves stability at high speeds. All this without compromising stiffness, making it ideal for the most powerful riders.
DEFY Seatpost Joint
The dual Y-shaped joint improves aerodynamics in the seatpost area and enhances vibration absorption, increasing comfort without sacrificing stiffness. Perfect for long breakaways and endurance stages.
Wind Tunnel-Verified Results
Tests conducted in real-world configurations show that the Y1Rs requires 20 fewer watts than the V4Rs to maintain a speed of 50 km/h. A significant advantage in fast races and windy conditions.
Modern Compatibility and Integrated Design
The Y1Rs is compatible with the most advanced electronic groupsets and offers a fully integrated design, from custom bottle cages to the aerodynamic seatpost. Every detail has been optimised to reduce weight and enhance aesthetics.
