The Super Record X Crank Arms embody Campagnolo's expertise in its purest form: a perfect balance of stiffness, lightness, efficiency, and distinctive design . The result of advanced engineering, they combine mechanical performance and functional aerodynamics , while preserving the legendary elegance of the Italian brand. The aeronautical-grade aluminum chainring features a completely redesigned tooth profile , inspired by the experience of the Ekar groupset, to offer precise chain engagement , smooth power transfer , and impeccable stability , even on the most demanding terrain.

The new surface finish improves wear resistance and ensures consistent performance in all conditions. Campagnolo offers a wide range of chainring sizes —38, 40, 42, 44, 46, and 48 teeth, expandable up to 52—to suit all riding styles, from endurance gravel to the fastest rides. Combined with 13-speed 9-42 and 10-48 cassettes , they form a modular and highly technological drivetrain system , offering unparalleled freedom of choice.

The exposed carbon fiber cranks , adorned with the exclusive Super Record X marking, embody Campagnolo's attention to detail and typical refinement. Their exceptional structural rigidity ensures maximum power transfer without any loss of efficiency.

Based on an Ultra-Torque steel axle optimized for gravel frames (Q-factor: 152 mm, chainline: 47.5 mm), the cranks incorporate low-friction QCK-Tech bearings , protected by a patented double seal against dust and mud. Available in lengths from 165 to 175 mm , the Super Record X redefines high-end drivetrains and the art of cycling by Campagnolo.
