Super Record 12x2 Speed Chainring Set

New Super Record 12x2 Speed chainring set: A super concentrate of innovation for maximum stiffness and shifting precision, all in a dedicated and aerodynamic design. The new Super Record 12x2 Speed chainring set, made from carbon fibers and featuring Campagnolo's Hollow Technology for reduced weight, utilizes the Ultra-Torque closure system with a titanium axle for total power transfer from the rider to the pedals. The new Super Record 12x2 Speed chainring set can be mounted on all frame models, whether with disc or other brakes, as it optimizes the chainline on frames with rear stops of 130, 135, or 142 mm without affecting the Q-factor, which remains at 145.5 mm thanks to the new crank arm shape.

The use of CULT ceramic ball bearings ensures the renowned smoothness typical of Campagnolo. The innovative shape of the outer chainring and the contoured pin guarantee faster and quieter upshifting. Additionally, the symmetrical tooth shape on the inner chainring enhances the stability of chain crossings. Together with the 8 fastening screws, the dual standard bolt circle (112 and 145 mm) optimizes weight and stiffness through increased use of carbon fibers. The varying number of pins for each of the three gear combinations (34/50, 36/52, 39/53) facilitates upshifting through optimal engagement of the individual combinations. Furthermore, the reliefs on the outer chainrings ease downshifting in the dead zones of the pedal stroke and improve performance.
