Colnago Y1Rs Ultegra Di2 Fulcrum - Carbon Roadbike - 2026 - YSBO

Built to defy wind.

Designed to conquer the wind, the Colnago Y1Rs is the epitome of aerodynamic efficiency. This bike was engineered to deliver optimal performance in the fastest races, featuring cutting-edge technology and innovative design for sprinters and breakaway riders. With a design that drastically reduces drag, stiffness optimized for the most powerful sprints, and surprising comfort over long distances, the Y1Rs offers a perfect balance of performance, efficiency, and control. 

Features of Colnago Y1Rs 

• Lightweight Colnago Y1Rs carbon frame
• Carbon fork with integrated cable routing
• Stiff and responsive
• Narrower front end
• Tires up to 32 mm

State-of-the-art aerodynamics

The Y1Rs reduces the 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 minimize drag and optimize airflow in all wind conditions.

Stiffness Where It’s Needed

The frame structure was designed to offer 3.5% greater stiffness compared to the previous model. This ensures immediate power transfer during the most intense sprints and unmatched responsiveness.

DEFY Seatpost Joint

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

Wind Tunnel-Tested Results

Tests in realistic configurations show that the Y1R requires 20watts less than the V4R to maintain a speed of 50km/h. A significant advantage in fast races and windy conditions.
