Top-quality aluminium wheels: the Eurus wheelset by Campagnolo
Lightweight design ready for any course and sturdy construction ready for the toughest terrain make this wheelset an easy choice. Thanks to the oversized flange and innovative G3™ technology, Eurus wheels have made a true leap to become a reference point for top end aluminium wheels.

Because finding the perfect wheel means having the correct information.
Campagnolo, in collaboration with professional racers as well as amateur enthusiasts, has identified 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?
S= 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 performance CULT™ ceramic ball bearings, USB™ ceramic ball bearings, or other technologies applied to the wheel such as 2-Way Fit™.
H =Handling: Many factors determine how well a wheel handles and to evaluate this indicator Campagnolo takes into consideration the geometry of the spokes, lacing patterns, hub design, cross section of the rim, materials employed and even the type of tyre to be used.
A = Aerodynamics: indicates the performance features of the wheel in terms of ist 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.
R = Reactivity: how " ready" and quick is the wheel in response to your change of pace on the pedals? The reactivity index of the wheel refers precisely to this concept.
Reactivity depends on the weight of the rim and of the wheel in ist 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 ist shape along ist axis when it is shifted, due to the push on the pedal, from the vertical axis), and on inertia.
C = 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.
The concept is simple and elegant: balance the weight of the gasket, with an item of similar weight placed on the exact opposite side. For top models, this is obtained by a special operation on the section of the rim opposite the rim joint (Rim Dynamic Balance™ = RDB).
A technology that offers several advantages to the structural integrity of the wheel as well as eliminating the need for rim tape. The name derives from " Mounting Magnet" system, shortened to MoMag™. How does it work? The nipples, once inserted inside the rim via the valve hole, are " guided" to the point of connection with the spoke by means of the magnet. This simple but ingenious system makes it possible to have a wheel without holes on the upper bridge, but with spokes tensioned by traditional nipples! Advantages: No holes on the rim means that the rim is uniform at every point, free from stress points or zones of weakness and, for the clincher profiles no rim tape is required, to the benefit of weight reduction. The advantages are immediately clear: greater rim lifetime, greater resistance to fatigue, the possibility to give the spokes greater tension, and greater stiffness which, in terms of performance, mean greater reactivity and acceleration. But that's not all. The advantages also include extremely quick and simple maintenance and spoke replacement. All to the benefit of cyclists who choose Campagnolo.
Campagnolo has developed an assembly architecture which, compared to 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™ geometry the right-hand side of the rear wheel is fitted with twice as many spokes as the left. The results of G3™ system are truly extraordinary: better transfer of the driving torque, better lateral rigidity, reduction of the stress in the rear wheel spokes. And thanks to the G3™ system that compensates for the forces acting on the 2 sides of the wheel, there are no more wheel vibrations, even for heavier people.
Spokes anti-rotation system™
Certain Campagnolo wheels feature a spoke anti-rotation system patented by Campagnolo that raises spoke performance to an unprecedented level. 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.
