ROTOR's lightest crankset yet, ALDHU's modular design allows you to custom build the perfect crankset to fit both your needs, and your bike's standards

ALDHU incorporates OCP Mount technology, which enables the rider to fine-tune the orientation of ROTOR’s oval Q RINGS. The ALDHU® proprietary, patent-pending design is based on the modularity of each crankset component

ALDHU 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
