Campagnolo Super Record WRL 2/12-speed carbon crankset UT

Super Record Wireless Crankset

The new Super Record Wireless 12x2-Speed crankset: Campagnolo's iconic design with exposed carbon fiber on a crankset developed for maximum performance. The Super Record Wireless crankset features a hollow, lighter structure and uses the Ultra-Torque fastening system with a titanium bottom bracket axle to transfer all the power the cyclist puts into the pedals to the drivetrain. The use of USB ceramic bearings provides the now familiar smoothness that has become a Campagnolo hallmark.

The Super Record Wireless crankset is part of the new drivetrain system, developed to offer an innovative gearing scheme (34/50, 32/48, 29/45) that, in synergy with the new cassettes, makes the widest range of metric development available. The Ultra-Torque system completes the specification, ensuring that all your power is converted into exceptional performance. Immediate and unstoppable acceleration eagerness along a titanium axle and lightweight carbon fiber crank arms. The chainring has been redesigned for uncompromising efficiency. Every watt of your power is transferred to the road. Project your performance into a new dimension.

Technologies

Ultra-Torque
Lightweight, stiffness, and simplified assembly: Ultra-Torque. Campagnolo has permanently joined the two halves of the bottom bracket axle to their respective crank arms. This new design significantly reduces the lateral bulk at axle height, avoiding unwanted contact with the ankle during pedaling. Operation is extremely simple: a single oversized screw connects the two axle halves. This was achieved through the use of a sophisticated mechanical system based on years of experience in rotating axle couplings: the Hirth joint. Essentially, it's a self-centering and self-aligning face gear joint, centrally positioned in the axis of motion, where the ends of the axle halves integrated into the crank arms come into contact. This system can be compared to a one-piece axle in terms of torque transfer efficiency, thus guaranteeing unparalleled power transfer efficiency.

User Centric Design
During the development of the Super Record Wireless groupset, the cyclist was placed at the center of the project. The user-centric philosophy is expressed in clear and immediate concepts: a functional and practical design to create a product where the interaction between human and machine is simple and direct. Whether for assembly, maintenance, or daily use, every shape and function of the Super Record Wireless groupset has been designed to offer maximum operating comfort. These concepts are also expressed in the innovative design of the Mycampy 3.0 App, which allows for immediate monitoring of the status of all components thanks to the revolutionary synoptic dashboard derived from aviation.
