Campagnolo's Eurus rear wheel is at the top end of the new generation of medium-profile wheels, characterized by the G3 spoke system and the 30mm rims. Eurus are a top class product, aerodynamic yet very light.
The rims are lightened via a special machining process. The unique G3 spoke configuration with variable cross section spokes connect to Record-class HPW hubs create an extremely light wheel that has the speed of high-profile wheels with the weight and comfort you'd expect from a low-profile wheel. This rear wheel provides record-breaking torsional and lateral stiffness thanks to the G3 system, which doubles right side spokes, reduces spoke tension, and gives an even lighter rim section.
