Thanks to the oversized flange and innovative Mega-G3 technology, Eurus wheels have made a true leep to become, alongside the Shamel Ultra, a reference point for top end aluminum wheels.
These high end wheelsets represent a big step ahead in terms of performance and reactivity. 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 optimizes the spoke tension and delivers a long lasting performance. Furthermore, Shamal™Ultra™ wheelsets 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.
Campagnolo has developed an assembly architecture which, compared with a traditional wheel, makes it possible to improve energy transfer, reduce the stress on the spokes on the right and increase transverse rigidity. This is achieved because in G3 geometry the right-hand side of the rear wheel is fitted with twice as many spokes as the left.
The results of G3 system are truly extraordinary: better transfer of the driving torque, better lateral rigidity, reduction of the stress in the rear wheel spokes. And thanks to the G3 system that compensates for the forces acting on the 2 sides of the wheel, there are no more wheel vibrations, even for heavier people.
G3 becomes Mega-G3 thanks to the oversize flange. This solution allows the increase of the torsional stiffness values even more, to the benefit of the overall responsiveness of the wheel.
Mega G3 Spoke Pattern
Perfect balance of the spoke tensions on both sides of the wheel. Reduces stress, increases transversal rigidity and the transmission of power to the wheel. G3 eliminates vibrations even with "heavy" cyclists.
The concept is simple and elegant: balance the weight of the gasket, with an item of similar weight placed on the exact opposite side. For top models, this is obtained by a special operation on the section of the rim opposite the rim joint. For entry-level models, Dynamic Balance is obtained by using two oversized spokes in the section opposite the joint. The result is a wheel with perfectly balanced rotational dynamics.
A technology that offers several advantages to the structural integrity of the wheel as well as eliminating the need for rim tape. The name derives from “Mounting Magnet” system, shortened to MoMag.
