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.
Our new model name comes directly from our 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.
One axle can be used for disc brakes or alternatively one for sweep brakes, which means a different Q-factor and chain line.
