- OVERVIEW
- SPECIFICATIONS
- SIZE CHART
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 kind
of competitions: 2 TDF GC, Monument Classics (Liegi, 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.
AERODYNAMICS
The V4Rs has been conceived as a fully-integrated system. While working on
the aerodynamics in order to reduce the overall drag, the superimposition
of effects simply doesn’t work. All the components must be developed and
tested together in order to prove the overall benefits. That’s why all the
presented data is obtained with the bicycle in race-ready configuration,
which means that it is equipped with head unit and 2 bottle-cages but one
bottle only (as in the crucial race phases).
This process of design and development started from the bike frontal area,
which has a huge impact on the drag, both directly (A factor in the formula)
and through its shape, by affecting the overall Cd factor.
INTEGRATION
The optimization of the frame frontal area involved an evolution of the head
tube geometry. Its shape has been revised and perfectly integrated with
the new lightweight fork (designed to allow an effective tire clearance up to
32mm) and with the new cockpit. Although the head set upper bearings are
bigger than those of the V3Rs, allowing the cables to run inside without the
need of the D-Shaped steerer column and enhancing the overall front-end
stability, the overall shape has a better drag. This, of course, required deep
surface modeling to keep the frontal area smaller and a better aerodynamic
shape factor.
V4Rs - The new cockpit CC.01
Although the V4Rs is compatible with third-party cockpits, the overall
platform has been optimized with the new Colnago cockpit CC.01, which
has a drag surface reduced by up to 16% compared to the cockpits mounted on V3Rs, and at the same time the shape has been designed as a NACA-
derived profile in order to have the minimum impact on the air flow, which is laminar and clean while impacting the components.
This aerodynamic evolution was carried out without reducing the cockpit’s
overall stiffness, which is as important as aerodynamics in sprint and
acceleration.Furthermore, for a perfect match and lower drag, the cockpit is offered also with the new 3D-printed, cyclo-computer support, compatible with Wahoo Bolt V2 (with further compatibilities yet to be announced). This detail, on top to the astonishing and clean aesthetics, also provide a measurable (!) 0.75
W* saving at 50km/h, which is highly relevant, considering the small area of
the component. *WAD = Weighted Average Drag (i.e. the sum of power at different yaw angles, weighed by the probability of occurring in such a condition).
PAVE
In the case of rough terrain, high-frequency impacts occur on both wheels
from the ground. These impacts combine with the stress caused by the forces from the cyclist’s body: his weight and the push on the pedals.
Innovative and racing-validated lamination
This result has been achieved thanks to the innovative carbon fiber
lamination featured on the V4Rs. For the ultimate racing machine, many
different layups featuring as many different stiffness matrices, have been
developed, tested and validated for professional use. The final call was given
to the riders themselves, who were provided for the most complete and
stressful competition of the year (TDF 2022) with “PROTOTIPO” with the
most promising layups, in order to bring the bicycle to real limit conditions
(on cobblestones, in sprints, on climbs and downhills) and provide data and
feedback to our engineers.
