Colnago was founded by Ernesto Colnago in 1954 in Cambiago, a small town east of Milan. From steel frames built for Eddy Merckx's five Tour de France victories to the carbon C-series that redefined Italian frame construction, Colnago has been at the center of professional road cycling for seven decades. The Y1Rs represents the brand's most radical departure — a wind-tunnel-born aero platform shaped by CFD simulation and 3D-printed modular testing, with deeply sculpted tube profiles and integrated bottle cages that sit flush with the frame. It rides closer to the V5Rs in feel than you'd expect from an aero bike, with a snappy, responsive character that reviewers consistently praise. Learn more at Colnago's official website.
Every custom Y1Rs build at RA Cycles starts with the frameset — frame, fork, CC.Y1 cockpit with computer mount, carbon seatpost, CeramicSpeed SLT bearings, and two Colnago x Elite custom bottle cages — then gets built to your spec with the groupset, wheels, and finishing kit of your choice. Five sizes from XS to XL. RA Cycles has been an authorized Colnago dealer for over fifty years.
