Colnago Y1Rs Disc 2025 Carbon Aero Road Bike – Dura-Ace Di2

Built to Defy the Wind. Engineered to Win.

The all-new Colnago Y1Rs Disc 2025 is a no-compromise aero machine, designed to deliver race-winning speed with unmatched efficiency. Tuned for sprinters and solo escape artists alike, it blends advanced aerodynamic innovation with proven WorldTour performance. With the latest Shimano Dura-Ace Di2 12-speed groupset, premium carbon construction, and cutting-edge integration, the Y1Rs is the definitive choice for time trials, criteriums and flat-out fast racing.

Optimised Aerodynamics & Power Transfer

Compared to the Colnago V4Rs, the Y1Rs reduces frontal area by 19%—a huge leap in aerodynamic performance. Thanks to the unique CC.Y1 integrated handlebar with WYND technology, a curved downtube, and a sleek DEFY seatpost junction, drag is dramatically reduced from every angle. At 50 km/h, the Y1Rs saves you 20 watts versus its predecessor—marginal gains that matter in elite racing.

Engineered with a 3.5% increase in frame stiffness, the Y1Rs guarantees explosive power transfer under maximum effort. The integrated gull-wing bars not only smooth airflow but offer unwavering stability during full-gas efforts—ideal for powerful riders chasing podiums.

Comfort Meets Control

Despite its aerodynamic edge, the Y1Rs doesn’t compromise on ride comfort. The dual Y-joint seatpost absorbs road buzz, making long breakaways and all-day rides more manageable without sacrificing performance. Paired with a modern carbon cockpit and CeramicSpeed SLT bearings, it offers a sublime balance of control and durability.
