Some bikes are fast. The Colnago Y1Rs is built to make the wind work harder. Colnago's ultimate aerodynamic road bike, the Y1Rs is designed for riders chasing every possible advantage when the pace goes up. Developed around the demands of modern WorldTour racing, it combines cutting-edge aerodynamics, exceptional stiffness and surprising comfort in one seriously uncompromising package. The Y1Rs reduces frontal area by 19% compared with the V4Rs, with its distinctive curved downtube and CC.Y1 integrated cockpit with WYND™ technology working together to manage airflow and reduce drag. The frame is also 3.5% stiffer than its predecessor, delivering the immediate power transfer and sharp response you'd expect when it's time to put the hammer down. Then there's the DEFY seatpost joint, designed to improve aerodynamics while helping absorb vibration for a more comfortable ride over long distances. Because being brutally fast doesn't mean you should have to suffer for it. The Y1Rs is a bike for the rider who wants the very best — and wants it built their way. Your Y1Rs. Your Build. We don't currently hold Y1Rs builds in stock, but that doesn't mean you can't get your hands on one. Talk to the Scotty Browns team about availability and we'll work with you to create your ideal Y1Rs build. We'll help you put together a bike that's every bit as individual as it is fast.
