The ROTOR ALDHU 3D+ crank arms form the foundation for road, cyclocross, and triathlon drivetrains. With a 170 mm crank arm length and a modular 30 mm axle system, they can be combined with compatible ROTOR components to create a suitable crankset.

Made from 7055 aluminum, these crank arms are designed for sport use. The modular ALDHU 3D+ system allows them to be combined with a compatible axle and suitable Direct-Mount chainrings or spiders.
