The Campagnolo Super Record 12V cranks provide a perfect innovation to obtain the maximum values ? of rigidity and deviation precision, all combined in an ultra rigid design that is aerodynamic at the same time. The Super Record cranks have a configuration based on carbon fiber lightened inside thanks to the Campagnolo technology "Hollow Technology", uses an Ultra-Torque locking system with titanium shaft to give the transmission maximum power to each pedal. They are compatible with all types of frames, whether disc brakes or not, as they optimize the chain travel in frames with a 130, 135 or 142 mm rear stop without affecting the Q factor, thanks to the new crank design it is maintained at 145.5 mm. The use of CULT ceramic bearings allows an extra softness in which Campagnolo has created a recognizable trademark. The new structure of the external plate consists of a profiled bolt that guarantees a faster and quieter uphill detour. The symmetrical design of the inner side teeth improves stability at chain crossings. The standard double diameter of the circle of bolts (112 and 145 mm) in combination with the fixing screws, allows to improve the weight and rigidity thanks to the use of carbon fiber. In each of the three combinations of plates uses a different number of bolts that favors uphill detour thanks to an optimized coupling for each combination. It also favors the diversion with the special discharges inside the outer plates in the dead spots of the pedaling, optimizing the performance.
