New 2023 Colnago V4Rs (Frame kit)

V4Rs is built to win. The bicycle is an extremely complex system made up of many parts, subsystems and components, and the numerous required performances can trade off between each other. When supporting a top-level team there is no room to neglect any single aspect: in one racing season, or even in one race or stage, there are several conditions and situations in which the rider who wants to win must not accept compromises. To develop a bicycle that performs the best in all racing conditions is a tough job, especially when the starting point is the V3Rs, a bike which is already a proven winner in all kinds of competitions: 2 Tour de France GC, Monument Classics (Liege, Lombardia), Classics (Strade Bianche and cobble-stone stages), sprint finishes, etc. The only possible way to evolve without neglecting any detail is to work directly and constantly in contact with the best and most demanding riders in the world: from the initial design inputs, to the final race validation, passing through all the development phases. The new Colnago V4Rs was built to do one thing:

BUILT TO WIN.

INCREASED OVERALL STIFFNESS

This frameset is stiffer than the V3Rs. You can sprint faster and climb with more efficiency. We developed a new testing methodology to simulate and measure stiffness in a realistic and effective way.

BETTER AERODYNAMICS

The V4Rs profiles have been revised to allow a decrease in aero drag. The Colnago V4Rs, albeit not an aerobike, is a significant leap forward compared to the V3Rs, based on its wind tunnel performances.The new V4Rs significantly improves the crash worth of the most exposed parts which may be subjected to impact in racing conditions. An example is given by the completely new designed seat stays, which, besides their more aerodynamic shape, also significantly improve the flexural and impact resistance. The robustness of this design also minimizes the need of maintenance.

BETTER HANDLING

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.

EASIER BIKE FITTING

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.
