Hands-On: Colnago Y1RS – Pogacar’s 2025 Tour de France Bike

Colnago has unveiled the Y1RS and Liam got hands on it to see just how unique this bike is in the flesh. The Y1RS is a radical new aero race bike, which is claimed to be faster than anything else on the market. It features tube shapes that make use of the UCI’s latest 8:1 depth-to-width rule and seatpost-placement regulation. Colnago says the result makes the Y1RS faster than the competition, potentially giving UAE Emirates team leader, Tadej Pogacar, the fastest bike in the peloton. But Colnago also claims to have made the Y1RS just as stiff as the V4RS, while claiming a weight of 7.45kg in a team build with pedals and cages. However, there are plenty of voices calling this a rather ugly duckling. Here are the crucial details, along with Liam’s first impressions.
