Rotor Aldhu Carbon Crank Arms
Rotor Aldhu Carbon Crank Arms Info
The Rotor Aldhu Carbon Crank Arms strip roughly 100 grams from the aluminum Aldhu without compromising the modular architecture that makes the platform so versatile. Carbon construction increases both vertical and horizontal stiffness compared to the alloy version — meaning more of your pedaling force reaches the drivetrain rather than flexing away into the crank body.
Rotor's Twin Leg design addresses a specific problem: power lost to axle torsion when force is applied through the left pedal. By balancing the load more evenly across the structure, the arms are designed to reduce those losses and keep your output consistent through the full pedal stroke. The 30mm axle interface is built for straightforward assembly with a secure, rattle-free fit, and full compatibility with Rotor's 1x and 2x direct-mount chainrings means you can configure the crank to suit your gearing needs without adapters or compromises.
