Campagnolo Record X 13 WRL 1X Power Meter Crank Arm Set

The Campagnolo Record X 13 WRL 1X Power Meter Crank Arm Set is the crankset at the center of Campagnolo's Record 13 X gravel platform, a wireless 13-speed groupset built for mixed-terrain and gravel racing. It's built on the proven Ultra-Torque system with a steel spindle and carbon fiber crank arms, and the 152mm Q-factor and 47.5mm chainline are sized specifically for gravel frame clearance rather than adapted from a road crankset.

Campagnolo's CPM power meter is built into the spindle itself, using 8 strain gauges and an integrated gyroscope to measure power on both crank arms independently, with a claimed accuracy of ±2%. Because the sensor reads torque directly off the spindle rather than crank arm flex, the numbers stay consistent no matter how hard you're standing on the pedals. Data streams live to the MyCampy app or a compatible head unit, and the battery charges through the same magnetic quick-snap connector used across the Record and Super Record 13 platform.

The single aerodynamic chainring uses a tooth profile developed from Campagnolo's Ekar gravel groupset for secure chain retention over rough ground, with eight sizes available from 38 to 52 teeth across the platform. The QCK-Tech bottom bracket's sealed, low-friction bearings are built to shrug off mud and dust. Crank arms come in 165mm, 170mm, and 172.5mm lengths for biomechanical fit.
