Lightweight, strong and almost endless crank arm, spindle and chainring set-ups

Clear selection


The all new ROTOR ALDHU Crank is CNC machined out of 7075-aeronautic grade aluminum to ensure unmatched rigidity from spindle to chainrings allowing you to take control on the roughest roads and terrain. The ALDHU features ROTOR’s Optimum Chainring Position (OCP) Mount technology which allows the rider to fine-tune the orientation of ROTOR’s Q Rings by shifting them one degree at a time, finding the right balance in each pedal stroke for smooth power.

ROTOR makes it easy to build the ALDHU crank to fit your needs. Crank arm sizes start as low as 150 mm and go through 175 mm. The crank is also available with either a 24 mm or 30 mm spindle to fit the bike frame and bottom bracket of your choosing. In addition, the ALDHU can fit a wide range of ROTOR chainrings, including round, oval, 1x and 2x.
