Frameset Purchase: This is a frameset purchase, not a complete bike. Included components are the frame, fork, headset, seatpost, finishing kit, and handlebars. Drivetrain, wheels, brakes, and all other components are sold separately. Product photos show a complete build for illustrative purposes.

The Colnago Y1Rs is the ultimate expression of aerodynamic efficiency in the Colnago lineup, designed specifically for sprinters and breakaway specialists who need every marginal gain the wind tunnel can find. Its frontal area is 19% smaller than the V4Rs, and wind tunnel testing in full race configuration confirms it requires 20 fewer watts to hold 50 km/h. The frame achieves this through a curved downtube, a proprietary Bayonet fork with fully integrated cable routing, and the DEFY dual Y-shaped seatpost joint - an innovation that simultaneously improves aerodynamics in the seat area and increases compliance without softening frame stiffness. With 3.5% greater stiffness than its predecessor and a development process grounded in CFD simulation and university collaboration, the Y1Rs is built for riders who race to win.
