Take control of your crankset with total modularity at a minimum weight with 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 allow 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.
Optimum Chainring Position (OCP) Mount technology allows the rider to fine-tune the orientation of ROTOR’s oval Q Rings by shifting them one degree at a time, finding the right balance in each pedal stroke for smooth power. This enables the rider to utilize the most powerful part of their pedal stroke to propel them further, and allow a touch of relief through the weakest points.
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.
Note: Price is for ALDHU crank arms only, and will require an Axle and Chainrings. Standard ALDHU is not compatible with 24mm ALDHU Axles.
