Over-Torque™:
This is the case with the latest development from Campagnolo® by the name of Over-Torque™ Technology. Engineers from the Campy Tech Lab™ set out to improve upon what were already considered to be exceptional cranksets.
The completely new Over-Torque™ product represents an increase in performance while also saving weight. Following the Campagnolo® philosophy of keeping the bearings at the widest stance possible with a large diameter axle the Over-Torque™ construction has an extremely wide stance for bearings in addition to a 30mm axle diameter.
