Always aiming at better performance, Campagnolo® has improved the wheel's efficiency by reducing its weight by no less than 70 g!
Tests run at our laboratories have shown that this is the solution that currently provides the best results in terms of performance and reliability: a light and very steerable front wheel and a stiff and responsive rear wheel. The rims have been lightened in toroidal form between the spoke insertion zones, i.e. in the section of the rim where diameters can be reduced without lessening the solidity of the structure The dynamic balance of the wheel is assured by special milling in the section opposite the joint. This balances the weight of the joint during rotation of the wheel. Both rims have a top bridge that is free of holes. This is a significant weight saving, thanks to the lack of rim tape, and gives the wheel greater torsional stiffness and greater vertical elasticity. The Ultra Aero™ aluminium spokes are butted and the front wheel has radial spoking whereas the back wheel has G3™ spoking. The rear rim has asymmetrical holes to obtain a better wheel dish. The hubs are in oversize aluminium with aluminium axles and self-aligning bearings. The rear hub has a larger flange to increase torsional stiffness and therefore wheel performance during acceleration and bursts of speed on the pedals. Eurus™ wheels use the freewheel body and pawl carrier housed in a single aluminium part for maximum lightness. The levers in cold-forged aluminium with two pivots grant a perfect and more balanced clamping. Eurus™ wheels are available in Black and Silver versions.
