Description
Colnago Y1RS Dura-Ace Di2 Limited Edition Road Bike
The Colnago Y1Rs Dura-Ace Di2 Road Bike is built to defy the wind and dominate at high speed, now presented in a limited edition Dark Titanium colourway that blends aggressive aerodynamics with a sleek, understated finish. Designed for sprinters and breakaway specialists, this cutting-edge machine pairs Colnago’s most advanced aero platform with Shimano Dura-Ace Di2 electronic shifting for instantaneous, race-ready performance, precision, and reliability.
With a frontal area 19% smaller than its predecessor, the Y1Rs integrates CC.Y1 handlebars with WYND technology and a sculpted curved downtube to optimise airflow in every wind condition. These aerodynamic refinements, combined with a 3.5% increase in frame stiffness, ensure explosive power transfer for full-gas sprints while maintaining sharp, confidence-inspiring handling at speed.
Every detail has been developed and validated in real-world racing scenarios to deliver measurable gains. The innovative handlebar and downtube profile minimise drag, the reinforced frame structure maximises stiffness for uncompromising power output, and the DEFY seatpost joint absorbs road vibrations to enhance comfort during long, high-speed efforts. Wind tunnel testing confirms a 20-watt saving at 50 km/h compared to the V4Rs, while full integration with advanced groupsets and components ensures seamless performance. In this exclusive Dark Titanium finish, the Y1Rs Dura-Ace Di2 is as striking as it is fast.
