COLNAGO Y1RS SHIMANO ULTEGRA DI2 Fulcrum Shark 57 2025 YSBC

The Colnago Y1Rs is the ultimate expression of aerodynamic efficiency. This bicycle is designed to provide optimal performance in the fastest races, combining advanced technology and innovative design for sprinters and breakaway specialists.

With a design that drastically reduces air resistance, optimized stiffness for the most powerful sprints, and surprising comfort on long distances, the Y1Rs offers the perfect balance between performance, efficiency, and control.

Every design decision was validated in the World Tour competition context. A project must not only look good on paper, it must also deliver exceptional performance in real conditions.

*Cutting-edge aerodynamics*

The Y1Rs reduces its 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 air resistance and optimize aerodynamic flow in all wind conditions.

*Stiffness where it matters*

The frame structure has been designed to offer 3.5% more stiffness than the previous model. This ensures immediate power transfer during the most intense sprints and incomparable responsiveness.

*CC.Y1 handlebar with WYND© technology*

The handlebar features a "seagull wing" shape that minimizes flow separation and improves high-speed stability. All this without compromising stiffness, making it ideal for the most powerful riders.

*DEFY seat tube junction*

The double Y-shaped junction improves aerodynamics in the seat tube area and better absorbs vibrations, increasing comfort without sacrificing stiffness. Perfect for long breakaways and endurance stages.

*Wind tunnel verified results*

Tests carried out in real configurations show that the Y1Rs requires 20 watts less 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 groups and offers a fully integrated design, from custom bottle cages to the aerodynamic seat tube. Every detail has been optimized to reduce weight and improve aesthetics.
