ROTOR's ALDHU 24 DM Cranks: Performance-Enhancing Modularity in Action
Take control of your crankset with total modularity at minimal weight with ROTOR's new ALDHU cranks. These streamlined cranks combine an innovative modular structure allowing complete axle and chainring adjustability to individually customize your ride based on your needs and preferred 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. This iteration of ALDHU pares the traditional 30mm version down to a 24mm spindle that offers the stiffness of steel paired with any 24mm bottom bracket.
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.
This crankset, with its variety of crank length options and compatibility with the INspider power meter, is the perfect upgrade solution for bikes that can only accommodate 24mm crank axles, such as Trek's BB90 standard.
Tune Your Ride with OCP Mount Technology
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.
The ALDHU name pays homage to ROTOR's racing heritage as an abbreviation of Alpe d'Huez, commemorating ROTOR's first iconic victory at the Tour de France with Carlos Sastre.
Rotor's Aldhu 24 DM Crank Arms are compatible with Rotor's Road Axle for Aldhu/Vegast Cranks.
