Take control of your crankset with complete modularity from ROTOR's new ALDHU cranks. These streamlined cranks combine an innovative modular structure with top-tier 7075-aeronautic grade aluminum, allowing you to adjust your axles and chainrings to individually customize your ride based on your needs, and your bike's standards.
It begins with the 3D+ CNC machining to ensure unmatched rigidity from spindle to chainrings so you can take control on the roughest roads. The ALDHU is available with two different 30-millimeter spindle options that offer stiff power, and room for rim brakes or disc brakes. A wealth of crank-arm lengths allows you to optimize your power, while OCP Mount technology lets you further fine-tune your ride with Q rings. The ALDHU’s proprietary, patent-pending design is based on the modularity of each crankset component.
The ALDHU's 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.
