Designed to defy the wind, the Colnago Y1Rs is the ultimate expression of aerodynamic efficiency. This bike is built to deliver optimal performance in the fastest races, combining advanced technologies and innovative design for sprinters and breakaway specialists.
With a design that drastically reduces air resistance, stiffness optimized for the most powerful sprints, and surprising comfort for long distances, the Y1Rs offers the perfect balance of performance, efficiency, and control.
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.
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.
The handlebars feature a "gull-wing" design that minimizes airflow separation and improves stability at high speeds. All this without compromising stiffness, making it ideal for the most powerful riders.
| Frame Size | Stem Size | Handlebar Size F-F |
|---|---|---|
| XS | 95 mm | 370 mm |
| S | 105 mm | 370 mm |
| M | 115 mm | 370 mm |
| L | 125 mm | 390 mm |
| XL | 125 mm | 390 mm |
Bars in different sizes will be available also to meet the fit requirements of each rider. Please discuss with your nearest Dealer to determine the correct handlebar size for your fit.
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.
Test conducted in real-world configurations show that the Y1Rs required 20 fewer watts than the V4Rs to maintain a speed of 50 km/h. A significant advantage in fast races and windy conditions.
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 optimized to reduce weight and enhance aesthetics.
Every design decision was validated in a World Tour racing context. A project shouldn't just look good on paper; it needs to perform exceptionally in real-world conditions.
