Product Description

Zonda is a reference model for aluminium wheels with rim brake in the mid-segment. As Campagnolo enters the world of disc brakes for the first time in its history, the company wants to achieve performance similar to that of a wheel with rim brake, even if the structure of a wheel with disc brake is completely different. The result is an even better acceleration performance achieved by the engineers at Campy Tech Lab. Both wheels are equipped with asymmetric rims and Mega G3 hubs to create a stable wheel set.

G3 geometry
Campagnolo has developed a spoking pattern that, compared to a conventional wheel, improves energy transmission, reduces the stress on the right spokes on the rear wheel and increases lateral stiffness. In the G3 geometry, the right side of the rear wheel has twice as many spokes as the left side. The advantages of the G3 system are amazing - improved power transmission, increased lateral stiffness, reduced spoke tension on the rear wheel. Thanks to the G3 system, vibrations are eliminated - even for heavier riders.

Dynamic Balance
The welded rim joint adds a few grams to one side of the rim. The problem is the unevenly distributed weight ratio caused by the magnet. The solution is Dynamic Balance. The mass of the rim joint is balanced with exactly the same mass. So the wheel runs perfectly balanced. In Campagnolo's top models, developers achieve this by special machining of the rim relative to the rim joint.

The "Mounting Magnet" is a magnet with a mind. That's why Campagnolo patented it. The spoke nipples are inserted into the rim through the valve opening and then guided to the corresponding opening by a magnet. The upper rim web is closed and clamping is done from the outside. The closed rim bed is more stable, no rim tape is required for clincher tyres, which saves additional weight. The spokes can be tightened and changed easily. The wheel is stiffer and more stable, making response and acceleration higher.
