Rotor ALDHU 3D+ crank axle with 24mm axle diameter. Also intended for use with the VEGAST crank.

ROTOR’s lightest crankset ever, the ALDHU's innovative modular structure makes each component individually available to accommodate the current spectrum of riders and bike standards. ALDHU axles independent of the crank arms enable the user to build a crankset unique to his or her bike set up. The ALDHU incorporates OCP Mount technology, which enables the rider to fine-tune the orientation of ROTOR’s oval Q rings. The ALDHU’s proprietary, patent-pending design is based on the modularity of each crankset component. The new model name comes directly from ROTOR's racing heritage. It is an abbreviation of Alpe d’Huez to commemorate ROTOR’s first iconic victory at the Tour de France with Carlos Sastre.
