Colnago Y1RS Frameset S YSBC

Designed for absolute speed and refined in collaboration with WorldTour sprinters and breakaway specialists, the Colnago Y1Rs Frameset represents the cutting edge of aerodynamic engineering. Engineered to maximize output during high-velocity efforts, it combines aggressive aerodynamic profiling with uncompromising stiffness.

• Riding Style: Aero Road / Competition / Breakaway & Sprint Specialist
• Key Highlight: 19% reduction in frontal surface area compared to the V4Rs, yielding a 20-watt savings at 50 km/h.

Key Technical Features

• Defy Wind Aerodynamics: Developed using advanced CFD modeling and wind tunnel validation with Khalifa University. Features a dual-plate head tube construction that slims down the front profile without sacrificing torsional stiffness.
• Real Riding Stiffness (RRS): Offers 3.5% greater power transfer efficiency through the bottom bracket, rear triangle, and cockpit over previous models, ensuring explosive responsiveness during all-out sprints.
• DEFY Y-Shaped Seatpost Joint: A distinctive rear-triangle joint that takes full advantage of UCI design rules. It contours around the rear wheel to minimize air turbulence while significantly enhancing vertical compliance for long-distance comfort.
• CC.Y1 Integrated Cockpit: Features WYND foil profiles with a subtle gull-wing drop bar design to maintain clean airflow attachment across all yaw angles.
