The ROTOR ALDHU24 165 mm crank arms are designed for riders looking to build a compact, sporty road or gravel setup. The short crank length supports a modern riding position and can feel especially comfortable at high cadence or on more technical sections.
Made from 7075-T6 aluminum and CNC-machined, the crank arms combine low weight with high stiffness. The modular ALDHU24 system allows pairing with compatible 24 mm crank axles as well as different chainring and spider solutions - allowing the drivetrain to be tailored to the intended use, chainline and gearing.
