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.

In the 2012 range the Shamal™ and Zonda™ wheels increase their responsiveness specifically thanks to this system. 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.
