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.
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.
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 optimized to reduce weight and enhance aesthetics.
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. This zone was designed on the basis of the new, more permissive UCI regulations on the development of bike shapes. The seatpost joint area is now a sort of union of two inverted ‘y’s’. The seatpost is misaligned in relation to the seat tube, which also has a different angle of inclination. The seat tube now follows the rear wheel, in pursuit of greater aerodynamic performance in a critical area for airflow. The seatpost, on the other hand, is more inclined than usual, ensuring greater compliance. The effect is a bike that - despite the increased stiffness of the frame - is pleasant to ride over long distances and in longer training sessions.

Integrated bottle cages
Standard bottles are not aerodynamic. However, they are the lightest and most practical solution both in races and in training. Colnago designed custom bottle cages to perfectly match the shape of the frame, minimizing the aerodynamic loss due to the bottles. Everything at a competitive weight and within UCI constraints. The downtube bottle cage also features support for a Di2 battery in the downtube, further easing mounting and maintenance.
Read Riding Stiffness Optimisation
Y1Rs is conceived to be the fastest Colnago road racing bike, and, consequently, the best choice for sprinters. WorldTour sprinters look for two main performances: aerodynamics and stiffness. Colnago has developed new testing setups and methodologies to measure the frame deformations in different points under multiple loads, to simulate what happens in real riding conditions. The deformations are then summed up in one number that Colnago calls Real Riding Stiffness.
