Campagnolo Super Record 13 WRL Crank Arm Set

The Campagnolo Super Record 13 WRL Crank Arm Set sits at the very top of Campagnolo's road drivetrain hierarchy — the crank arm set built for riders who want the flagship Super Record 13-speed wireless groupset performing at its full potential. These arms are engineered around Campagnolo's Ultra-Torque system, a design philosophy focused on reducing drivetrain flex and delivering power directly to the drivetrain without compromise. If you're building or upgrading a high-performance road bike around the Super Record 13 WRL ecosystem, this is the component that anchors it.

Construction is exposed carbon fiber throughout, chosen for its stiffness-to-weight ratio and the characteristic aesthetic that distinguishes Campagnolo's top-tier components. The Ultra-Torque interface uses a titanium semi-axle — titanium rather than steel to keep mass down while maintaining the structural integrity needed under hard accelerations and sustained power output. The surface finish is refined to improve wear resistance over time, meaning the arms hold up through extended use in variable conditions without the kind of surface degradation that affects lesser materials. Four arm lengths — 165mm, 170mm, 172.5mm, and 175mm — give you the range to dial in your fit and optimize your pedaling biomechanics rather than compromise around a one-size-fits-most option.

Design Benefits

1. Ultra-Torque with titanium semi-axle: The Ultra-Torque system is designed to minimize lateral flex at the bottom bracket interface, keeping your power transfer as direct as possible. The titanium semi-axle reduces rotational mass without sacrificing the structural rigidity the system depends on.
2. Exposed carbon fiber construction: Rather than a painted or wrapped finish, the raw carbon layup is left visible — a deliberate choice that reflects both the manufacturing precision involved and the material's inherent stiffness properties. The refined surface treatment is intended to resist wear under demanding riding conditions, maintaining consistent performance across a long service life.
3. Four arm lengths for a dialed fit: Crank arm length has a measurable effect on hip angle, knee tracking, and sustainable power output. Offering 165mm through 175mm in a single product line means riders at both ends of the fit spectrum — from smaller-statured road racers to taller riders with longer femurs — can run the correct length rather than adapting their position to what's available.
