Colnago V4Rs Disc frame

The V Series Colnago means just one thing: a frame made for winning races

Every detail is curated and optimized to let Pro riders dominate the most important races WorldWide, such as Monuments and Tour de France.

Aerodynamic data
The performances of V4Rs are those of an aero frame. 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) Colnago 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 frame had an aerodynamic saving of 6% (approx. 27.7 watts saved)

Accurate measuring
Colnago created internal methodologies to replicate the loading forces of standing-on-pedals and seated positions, and check the overall frame deformation and stiffness. Colnago was able then to define what it called RDS (Real-Dynamic Stiffness), and characterize them in combined multi-load conditions.

Seated position
In the seated position, loads are applied only on the same plane of the front triangle to replicate all-round riding: Taking the V3Rs as reference value, the V4Rs results as 5% stiffer in this occasion.

Robustness
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.

The frame includes:

• Headset
• Seatpost
• Through-bolt hh12
