The Campagnolo Super Record 12s™ Ultra Torque™ crankset is more than just the representation of Italian passion for cycling and design. It is an intense concentration of innovation and technology, resulting in the greatest possible stiffness, maximum shifting precision as well as efficient power transfer and aerodynamics. The developers of Campagnolo have moved the Ultra Torque™ bolt of the crankset to the left side to eliminate the previously required opening on the driveside, which proves advantageous for aerodynamics and stiffness. The combination of extremely smooth-running CULT ceramic ball bearings, a stiff and very lightweight titanium axle and hollow crank arms made from unidirectional carbon fibres provides excellent performance efficiency on the road. In order to meet the special requirements of Campagnolo’s 12-speed groupsets, the distance between the chainrings has been adapted to the smaller chain. Besides, the chain line has been moved further outwards to fit both conventional road bikes with rim brakes and 130 mm hub width and disc road bikes with a hub width of 135/142 mm – for uncompromising shifting performance.
· Full compatibility with disc and rim brake frames
· Proven Q factor of 145.5 mm for unchanged pedalling biodynamics
· Hollow Technology™: hollow crank arms made of unidirectional carbon fibres allow for a low weight and maximum stiffness for efficient power transfer
· Coupled crank arms in the zones subject to greater force applied by the cyclist for maximum stiffness and improved aerodynamics
· Optimised design for every chainring combination (50/34, 52/36, 53/39)
· Surface treatment of the chainrings for increased durability
· Contoured shift pins on chainrings for smoother up- and downshifting in any chainring combination
· Ultra Torque™ bottom bracket technology: Despite the low width, the bottom brackets are located outside of the crankset and allow for a larger axle diameter. Thanks to the resulting increased support, the Ultra Torque™ technology achieves maximum stiffness values.
