Campagnolo Super Record/EPS crankset carbon 12-speed 50/34 teeth

Design". The new crankset Super Record 12x2 Speed in carbon fiber, whose weight has been reduced internally thanks to Campagnolo "Hollow Technology", uses the closing system Ultra-Torque with titanium shaft for a total transmission of the force exerted by the rider on the pedals. The new crankset Super Record 12X2 Speed can be mounted on all frame models, both with disc brakes and with other brakes, optimizing the catenary on frames with rear stop of 130, 135 or 142 mm, without compromising the Q-factor, which remains at 145.5 mm thanks to the new pedal crank shape.The use of ceramic ball bearings CULT ensures the well-known smoothness typical of Campagnolo. The innovative shape of the outer chainring and the contoured pin guarantee faster and quieter upshifting. In addition, the symmetrical tooth shape on the inner chainring improves the stability of the chain crossings. Together with the 8 mounting bolts, the double standard bolt circle (112 and 145 mm) optimizes weight and stiffness through increased use of carbon fiber. The different number of bolts for each of the three gear combinations (34/50, 36/52, 39/53) facilitates upshifting by optimally engaging each combination. Furthermore, the reliefs of the outer chainrings facilitate downshifting in the dead zones of the pedaling motion and improve performance. - Intended use: road bike - Weight: 618 g - Details: - Q-factor 145.5 mm - Material specifications: Carbon material - Crank arm(s): Carbon fibers - Small chainring: Aluminum - Large chainring: Aluminum chainrings - Number of chainrings: 2 chainrings - Gear ratio: 50/34 teeth Crank - Axle mount: Ultra Torque - Bolt circle: 112/145 mm - Bolt circle type: Campagnolo - Chainline: 43.5 mm - Rear shift compatibility: 12-speed - Construction: 4-arm.
