Y1Rs Frameset
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.

Why we like the Colnago Y1Rs Frameset
The DEFY Joint Solves a Real Problem
The dual Y-shaped seatpost joint is an original piece of frame engineering that does two things at once: it narrows the aero profile in the seat tube area, and it creates a degree of vertical compliance in the rear of the frame. For riders covering long races at high speed on imperfect roads, that compliance is not a luxury - it is what keeps the legs fresh for the sprint.
20 Watts is a Race-Winning Margin
The 20-watt saving at 50 km/h is not a claimed figure from an optimised wind tunnel setup - it was validated in a full race configuration with mannequins replicating the actual position of WorldTour riders. At the speeds where sprints are won and lost, that margin is the difference between leading out and catching a wheel. It is an unusually concrete and honest performance claim.
Pogacar's Weapon of Choice for Fast Racing
Tadej Pogacar - reigning World Champion and multiple Tour de France winner - reaches for the Y1Rs when the race demands pure speed. On the flat stages, classic sprints, and high-speed finales where aerodynamic advantage is decisive, this is the frame he trusts. Riding the same platform as the best cyclist in the world is a meaningful benchmark, not a marketing footnote.
