To optimize the key features of a road bike wheelset, such as weight, aerodynamic and stiffness, engineers at Campy Tech Lab are always working hard implementing new technologies. One of the new results of these efforts is the Mega G3 Geometry, the further development of the G3 Geometry, which optimises the spoke tension and delivers a long lasting performance. Furthermore, The Campagnolo Eurus Clincher Wheelset, mount a new oversize drive side flange on the rear wheel that is now bigger and allows to increase dramatically the responsiveness of the wheels and the overall performance of the bicycle. The Eurus has aluminium hub bodies which serve a greater stiffness and include steel balls bearings to guarantee a long lasting performance. Because of the cup and cone system, the bearings are more adjustable and easily to maintain.
