Designed by the Campy Tech Lab engineers according to a precise objective: to create a crankset that is easy to maintain, lightweight, & that retains the same U & Q factors of its "big brother" Ultra-Torque. But that wasn't enough. Our engineers wanted to do more; i.e. to drastically improve shifting performance. The ultra-high quality bearings, positioned in the most extreme points of the central axle, guarantee the maximum smoothness & perfect efficiency of the pedalling over time. The Power Torque System used for the Centaur crankset is the ideal solution for the Campagnolo 10s drivetrains, with high rigidity of the cranks & chainrings along with an extremely limited weight, to achieve the most efficient power transmission.
