Campagnolo Zonda Roadwheels (Silver). The Zonda™ wheels have been restyled and weigh just 1,610* g, a full 100 g less than in the previous version. Campagnolo® is this year introducing the concept of a differential profile for the Zonda™ and Eurus™ models, i.e. a 24-mm profile for the front rim and a 28-mm profile for the rear rim. Tests run at our laboratories have shown that this is the solution that currently provides the best results in terms of performance and reliability. This solution in fact gives a light and very steerable front wheel and a stiff rear wheel that maximizes the transmission of the rider’s leg power. Both rims have been lightened between the zones in which the spokes are inserted, i.e. the section of the rim where diameters can be reduced without diminishing solidity.

Weight Front 675gms, Rear 935gms.

Special milling in the section opposite the joint ensures dynamic balance during rotation of the wheel and prevents a “jump” being felt at high speeds.

Both rims have a upper bridge that is free of holes. This means weight saving because rim tape does not need to be fitted and gives the wheel greater torsional stiffness and vertical elasticity.

The Ultra Aero™ stainless-steel butted spokes are arranged radially on the front wheel and the rear wheel has G3™ spoking. The rear rim has asymmetrical holes to improve wheel dish.

The hubs are oversize with aluminium axles and self-aligning bearings. The flange of the rear right-hand hub is oversize to increase torsional stiffness.

Zonda™ hubs also use the new freewheel body and pawl carrier housed in a single aluminium part for maximum lightness.
