The Colnago Y1Rs is built for riders who demand the fastest, most efficient race machine. Designed to cut through the wind with unrivalled aerodynamics, deliver explosive stiffness for sprints, and provide comfort for long days in the saddle, the Y1Rs represents Colnago’s most advanced road racing platform to date.
Aerodynamic Excellence
Compared to the Colnago V4Rs, the Y1Rs reduces frontal area by 19%, thanks to innovations like the CC.Y1 integrated cockpit with WYND© technology and a uniquely curved downtube. These features optimize airflow and reduce drag in real-world race conditions.
Stiffness Where It Counts
The Y1Rs frame delivers 3.5% greater stiffness than the previous model, ensuring instant power transfer for maximal efficiency during high-intensity sprints and attacks.
DEFY Seatpost Joint
The Y-shaped joint in the seatpost area reduces turbulence and absorbs road vibrations without sacrificing stiffness—ideal for breakaways and endurance efforts.
Proven in the Wind Tunnel
Testing shows the Y1Rs saves 20 watts at 50 km/h compared to the V4Rs, giving riders a decisive edge in high-speed racing and crosswinds.
Seamless Integration
From the hidden cabling to the aerodynamic seatpost and custom Colnago x Elite bottle cages, every detail of the Y1Rs has been designed for speed, lightness, and clean aesthetics.
