Introducing the Aldhu cranks, Rotor’s lightest cranks ever. The innovative modular structure, together with axles and different chainring options, makes each component individually available to accommodate the current spectrum of riders and bike standards. The 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. 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.
