Colnago Y1Rs – Aero Road Bike for Maximum Performance
Designed to defy the wind
The Colnago Y1Rs is the essence of aerodynamic engineering applied to road cycling. Ideal for sprinters, breakaway specialists, and riders who want to dominate high-speed races, this bike is the result of years of research, wind tunnel testing, and technological innovation.
Thanks to a 19% reduction in frontal surface area compared to the V4Rs, the Y1Rs guarantees superior aerodynamic penetration, without compromising rigidity and comfort, even on the longest rides.

A Complete Guide to Bike Sizes
Foreword: Not all bike sizes are the same
Each type of bike has a specific frame and often uses a different size scale. For example, a road bike with a 54cm frame might be considered a medium size by one brand, but a large by another.
Bicycle adjustment margins
Some types of bikes, like gravel bikes, offer a wide range of adjustments, adapting to different body types. Other models, however, have limitations in this regard. This is an important aspect to consider.
How to use size charts
We've created a simple guide to help you find the right bike size:
- Check out our size charts for each bike type.
