Custom Colnago Y1Rs Road Bikes

Custom Colnago Y1Rs Road Bikes

The Colnago Y1Rs is the bike Tadej Pogačar rode to a fourth Tour de France, a second consecutive World Championship, and a record fifth Il Lombardia — Colnago's first clean-sheet aero road bike, developed with Politecnico di Milano and validated at the highest level of professional racing. A 19% reduction in frontal area over the V4Rs and 20 fewer watts at 50 km/h, wrapped in a frame that weighs 965 grams and clears 32mm tires. H.U.L.C. carbon fiber, BSA threaded bottom bracket, CeramicSpeed headset bearings, and the CC.Y1 integrated cockpit with WYND crosswind technology come standard.

Choose your groupset below — Shimano Di2, SRAM AXS, or Campagnolo Super Record WRL — and we'll build your Y1Rs by hand, specced exactly the way you want it.

About the Colnago Y1Rs

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.

50 YEARS AND COUNTING

That half-century belongs as much to you as it does to us. The riders who kept coming back, who sent their friends, who trusted us with bikes that matter — you're the reason we're still here. Here's to the next fifty.
