The Colnago V4 is an all-round bike, extremely fun to ride and with a clean and refined design. The frame is a rigid, solid and reactive monocoque frame, which benefits from the same research and development on the carbon layup and the same aerodynamic studies that led to the creation of the V4Rs.

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.
