The Campagnolo Super Record 12 Speed Crank-set is an intense concentration of innovation that results in the greatest possible stiffness and precision in derailing, whilst providing a dedicated aerodynamic "super design". The new carbon fiber Super Record crank-set has been made lighter on the inside through Campagnolo Hollow Technology, which uses the Ultra-Torque bottom bracket system with a titanium axle to transfer all of the force the athlete applies to the pedal to the drive-train.
This crank-set can be installed on any type of frame, whether or not it is being used with disc brakes because it optimizes the chain line on the frame with a rear hub flange measuring 130, 135 or 142 millimeters, without affecting the Q factor, which remains constant at 145.5 millimeters thanks to the new crank design. The use of ceramic Cult bearings leads to obtaining the smooth ride that the Campagnolo brand is known for. The innovative design of the outer chain-ring ensures faster, quieter derailing owing to the contoured pin. The symmetrical design of the inner chain-ring teeth allows improved stability with chain crossovers. The double wheel sizing standards (112 and 145 millimeters) combined with the eight fixing screws, optimizes weight and stiffness through the increased use of carbon fiber. The varying number of pins for each of the three chain-ring combinations (34/50, 36/52, 39/53) facilitates up-shifting due to the optimized free strokes associated with each combination. The special drains on the inside of the outer chain-rings optimize performance when downshifting in dead spots.
