Acceleration-friendly and stable: the Zonda DB Wheel by Campagnolo

Zonda is a reference model for aluminium wheels with rim brakes for intermediate use. With this model, Campagnolo entered the world of disc brakes for the first time in its history. The company wanted to achieve performances that echoed wheels with rim brakes, even though the structure of a wheel with disc brakes is completely different. The result is even better acceleration, utilising asymmetric rims and Mega G3™ hubs to create a stable wheel that absorbs the energy of the braking torque generated on the left side and ensures the strongest power transmission on the right side at the rear.

Not all wheels are the same, nor are all riders. That's why Campagnolo, in collaboration with professional riders and cycling amateurs, has identified the 5 most important indicators that will help you choose the wheel that best suits your riding style and requirements.
What does S.H.A.R.C. mean?
S = Smoothness: Helps you compare the smooth running characteristics of the wheels, e.g. through the use of CULT™ high-performance ball bearings or USB™ ceramic ball bearings or other technologies used in the wheel, such as 2-Way Fit™.
H = Handling: This means agility and responsiveness of the wheel when changing direction in response to input from the rider. This index relies on the geometry of the spokes and hub, the cross-section of the rim, the materials used and the type of tyre.
A = Aerodynamic: Indicates the performance of the wheel in terms of air penetration. This depends on the height and profile of the rim, the cross-section and shape of the spokes and the spoke position (symmetrical/asymmetrical) of the wheel.
R = Reactivity: How " willingly" and quickly does the wheel react to a change in your pedalling rhythm? The wheel's reactivity index relates precisely to this concept. Reactivity depends on the weight of the rim and wheel as a whole, torsional stiffness (i.e. how much the wheel deforms around the hub when the rider pedals), bending stiffness (i.e. how well the wheel maintains its shape in the axle when it moves out of the vertical axis due to pedalling load) and inertia.
C = Comfort: Do you prefer a wheel that softens the unevenness of the ground or one that remains absolutely and uncompromisingly stiff? The " comfort" index is intended to help you understand how the wheel behaves when the road surface is not perfectly smooth or how much the wheel transmits vibrations to the frame.

Dynamic Balance™
The concept is simple and ingenious: balance the mass of the rim joint with an equivalent mass positioned exactly on the other side of the rim. In top-of-the-range aluminium models, this is achieved by special machining in the area opposite the rim joint(Rim Dynamic Balance™ = RDB).

A magnet and a lot of expertise. This is how the patent of the tested " Mounting Magnet" system, i.e. MoMag™, came to be. How does it work? After the nipples have been inserted into the rim via the valve opening, they are " guided" to the connection point with the rim using a magnet. With this simple and ingenious system, you get a wheel with no holes on the upper rim, but with conventional nipples for lacing! Advantages: no drilling in the rim bed, which means a consistently even rim without critical points or fractures, and no rim tape is necessary for wired tyres, which has a positive effect on the weight. The advantages are immediately obvious: longer rim durability, higher resistance to fatigue, possibility of tighter tensioning of the spokes and greater stiffness; in terms of performance, this means higher reactivity and acceleration. What's more: Replacing and maintaining spokes becomes extremely simple and fast. All to the benefit of the cyclist who has chosen Campagnolo.

Campagnolo developed a lacing pattern that, compared to a conventional wheel, allows improved energy transfer, reduces the stress on the spokes on the right side and increases lateral stiffness. In G3™ geometry, the right side has twice the number of spokes compared to the left side.
The advantages of the G3™ system are astonishing: better power transfer, greater lateral rigidity and reduction of spoke tension on the rear wheel. Thanks to the G3 system™, which compensates for the forces acting on the 2 sides of the wheel, vibrations are eliminated even for people with heavier weights. G3™ becomes Mega-G3™ thanks to the oversize flange. This solution further increases the torsional stiffness and thus improves the overall responsiveness of the wheel.
