campagnolo
®
wheels’ pursuit of high performance
while maintaining extremely high quality and
reliability levels, is the goal that engineers at campy
tech lab
tM
pursue every day in order to offer
campagnolo
®
fans even higher performing products.
cUlt
tM
: ceramic Ultimate level technology
tM
.
The quality of Campagnolo
®
wheels is guaranteed,
as always, by painstaking manual assembly carried
out by expert fitters using the strictest construction
standards.
Behind this project is the exclusiveness of Cronitect
®
steel; using “Advanced by FAG” technology by Scha-
effler Group employed for the bearing races.
This is steel which takes resistance to corrosion to the
highest level; to the point that, no grease is necessary
for lubrication, just a small amount of oil.
cUlt
tM
is a solution that increases the smoothness
of ceramic ball bearings and takes them to the
next level.
2-Way Fit
TM
is the – profile which makes it possible to
fit both a tubeless tiretire or a classic clincher.
With 2-Way Fit
TM
, Campagnolo
®
customers will be able
to personally test which of the two solutions suits
them best or use the clincher for training and the
tubeless tire for the day of the race.
With no doubt tubeless tires are the future of road
cycling. Apart from greater comfort, the advantages
are many: using a tubeless tire you can exploit the
greater smoothness due to the absence of friction
between the tiretires and the tube. There are no risks
of sudden deflation when a tubeless tire is punctured,
a great advantage in safety terms.
The lack of tubes eliminates puncture risks.
And what if the tubeless tire has a puncture? The
Campagnolo
®
2-Way Fit
TM
system allows you to use a
traditional inner tube by simply removing the hermetic
closure valve to ride home with no problem.
The design we have employed for our rims using
Ultra-Fit
TM
Tubeless technology allows the sidewalls
of the tire to mate perfectly with the shoulders of the
rim.
In our tests Ultra-Fit
TM
Tubeless wheels far surpassed
any other wheel fitted with a traditional tire.
All energy loss is eliminated by excluding all possible
movement between the rim and the tubeless tire.
Tubeless tires are exceptionally smooth and have less
rolling resistance than traditional clinchers.

has a long-standing reputation for the
extremely high performance of its hubs in terms of
smoothness and reliability.
In fact, all the projects are entirely developed in our
R&D department Campy Tech Lab
TM
and we have put
obsessive care into taking care of every detail.
The hubs with USB
TM
ceramic bearings (Ultra Smooth
Bearings) further enhance the wheels’ smoothness and
reduce weight and the need for maintenance.
Comparative tests have shown that USB
TM
bearings are
50% smoother than standard bearings.
Now improving your performance during the race or
simply going for a ride with your friends will be easier.

QUICK RELEASES

index
No two wheels are alike, and no two riders.
This is why Campagnolo
®
, in collaboration with profes-
sional racers as well as amateur enthusiasts, has identi-
fied and developed the five most significant indicators
that will allow you to choose the best wheel for your
riding style and your needs.
What does S.H.A.R.C. stand for?
Smoothness:
This indicator helps you understand the
degree of smoothness of one wheel with respect to
another thanks, for example, to the use of high perfor-
mance the CULT
TM
ceramic ball bearings, or the USB
TM
ceramic ball bearings, or thanks to other technologies
applied to the wheel such as 2-Way Fit
TM
.
Reactivity:
How “ready” and quick is the wheel in re-
sponse to your change of pace on the pedals? The reac-
tivity index of the wheel refers precisely to this concept.
Reactivity depends on the weight of the rim and of the
wheel in its entirety, on the torsional stiffness (i.e. how
much the wheel deforms around the hub at the moment
in which the cyclist pushes on the pedals), the flexional
stiffness (i.e. the extent to which the wheel maintains its
shape along its axis when it is shifted, due to the push
on the pedal, from the vertical axis), and on inertia.
Comfort:
Do you prefer a wheel that can absorb the
ruggedness of the terrain or an absolutely rigid wheel
with no compromise? It depends on your driving style
and your particular needs.
The comfort index aims to help you to understand
the behaviour of the wheel in the case of roads that
are not perfectly smooth, and in any case to help you
understand the extent to which the wheel transmits the
vibrations of your bike.
Campagnolo
®
provides you with all the technical infor-
mation, but now it’s up to you to decide which is the
perfect wheel for your needs! Your passion, your way
of riding your bike, and your feeling will enable you to
make the best choice.
They are not an accessory. Quick releases are
extremely important safety elements.
This is why Campy Tech Lab
TM
is always in search of
new, safer and more user-friendly solutions.
The increased cam effect, already introduced on last
seasons’ releases, resulted in great satisfaction and
appreciation.
SPOKE
ANTIROTATIONSYSTEM
The Campagnolo
®
Hyperon
TM
One, Zonda
TM
and
Bora
TM
One wheels feature a spoke antirotation
system patented by Campagnolo
®
that raises spoke
performance to an unprecedented level.
The Campagnolo
®
designers studied the spoke-hub
interface from the ground up to create a coupling
system that would keep the spokes always in the
exact identical position. This means that the spokes
of Campagnolo
®
wheels do not rotate, so there is
no loss of tension during use and the aerodynamic
penetration is not compromised.
Handling:
This is the agility and reactivity of the wheel
in changing direction at a given impulse on the part of
the rider. This indicator depends on the geometry of the
spokes and of the hub, and on the cross-section of the
rim, the materials used, and the type of tire.
Aerodynamic:
Indicates the performance features of
the wheel in terms of its propensity to penetrate the air.
This factor depends on the height and profile of the rim,
the section and form of the spokes, and the degrees of
camber of the wheel.

geometry: we have reinvented the wheel …
not just its look.
Campagnolo
®
has developed an assembly architecture
which, compared with a traditional wheel, makes it
possible to improve energy transfer, reduce the stress
on the spokes on the right and increase transverse
rigidity.
This is achieved because in G3
TM
geometry the right-
hand side of the rear wheel is fitted with twice as
many spokes as the left.
The results of G3
TM
system are truly extraordinary:
better transfer of the driving torque, better lateral
rigidity, reduction of the stress in the rear wheel
spokes.

LOW-PROFILE
WHEELS
Long demanding ascents, nervy paces, continuous restarts. When the weight of the
rotating mass is the first parameter to keep as low as possible, the ideal wheel is a low-
profile Campagnolo one. It has the beauty of designs which are elementary and natural
while being geometrical too.
®
These wheels guarantee the right balance between lightness, effectiveness of
torque transmission and absorption of the vibrations from the road surface.
