The choice of ProTour UAE Team Emirates for the 2023 Tour de France. The Colnago V4Rs is a leap forward from the tow time Tour winning V3Rs with improved aerodynamics, stiffness and feel.
The performances of V4Rs are those of an aero bike.
Compared to the V3Rs, in a real race setup (tested in the wind tunnel with an athlete pedalling at 50kph with 1 bottle and one empty bottle cage) we measured an aerodynamic saving of 3%, corresponding to approx. 13.2 watt. With an advanced aero setup (aero wheels and aero Colnago Computer support) the bike had an aerodynamic saving of 6% (approx. 27.7 watts saved)
The weight distribution has changed from the V3Rs. The front fork is now lighter and the overall weight of the frame kit + handlebar setup has been decreased of 56 grams.
The result is a better handling in corners and more safety and precision when going downhill.
Geometry has been revised to have even more balanced performance in all the different sizes with respect to the V3Rs. For the V4Rs the relationship between seat tube length and reach is almost linear, the stack / reach ratio has been optimized and harmonized among all the sizes, and the chain stay length has been reduced. This geometry affords a better balance, power transfer and the same race feeling for all the sizes.
