COLNAGO Y1RS DISC DURA-ACE DI2 VISION SC45 POWERMETER BIKE

Racing Against the Wind
The Colnago Y1Rs represents the ultimate in aerodynamic efficiency. Designed to deliver peak performance in the fastest races, this bike combines advanced technologies and innovative design for sprinters and breakaway specialists. With drastically reduced air resistance, optimized stiffness for powerful sprints, and surprising comfort over long distances, the Y1Rs offers the perfect balance of performance, efficiency, and control.

Cutting-Edge Aerodynamics
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 drag and optimize airflow in every wind condition.

Stiff Where It Counts
The frame structure is engineered to be 3.5% stiffer than the previous model. This ensures instant power transfer during high-intensity sprints and unmatched responsiveness.

CC.Y1 Handlebar with WYND Technology
The handlebar features a "seagull wing" design that reduces airflow separation and enhances stability at high speeds. All without compromising stiffness, making it ideal for the most powerful riders.

DEFY Seatpost Junction
The Y-shaped twin junction improves aerodynamics around the seatpost area and absorbs vibrations more effectively, increasing comfort without sacrificing stiffness. Perfect for long breakaways and endurance stages.

Wind Tunnel Proven Results
Real-world configuration testing shows that the Y1Rs requires 20 watts less than the V4Rs to maintain a speed of 50 km/h. A significant advantage in fast and windy races.

Modern Compatibility & Integrated Design
The Y1Rs is compatible with the most advanced electronic groupsets and features a fully integrated design — from custom bottle cages to the aerodynamic seatpost. Every detail has been optimized for reduced weight and improved aesthetics.

CFD Optimization
The design process begins with advanced Computational Fluid Dynamics (CFD) simulations, analyzing airflow around the frame and components. Colnago collaborates with leading universities to refine these models, ensuring they accurately reflect real-world aerodynamic conditions.
