ROTOR Aldhu 30 Crank Arms
Category: Bike Parts
Subcategory: Cranks
Experience the pinnacle of cycling performance and personalization with the ROTOR Aldhu 30 crank. Engineered for the most demanding road cyclists, the Aldhu represents a new standard in lightweight, stiff, and exceptionally modular crankset design. Its name, a nod to ROTOR´s racing heritage from the Alpe d’Huez, is a promise of elite-level performance on every ride, from grueling climbs to explosive sprints.
The core philosophy behind the Aldhu 30 is unparalleled customization. This innovative system allows you to select and combine each part of the crankset independently to perfectly match your physiology, riding style, and bicycle. The result is a component that feels tailor-made, delivering maximum efficiency and comfort. The featherlight construction, achieved through advanced CNC machining and the proprietary Trinity Drilling System, bores three internal holes along the crank arm, removing excess material while maintaining exceptional structural stiffness. This class-leading stiffness-to-weight ratio ensures every watt of your power is transferred directly to the drivetrain, providing instant acceleration and a responsive pedaling feel without any energy loss.
Furthermore, the Aldhu 30 features ROTOR´s groundbreaking OCP Mount technology. This spline interface allows you to micro-adjust the position of your oval Q RINGS chainrings with one-degree precision, enabling you to fine-tune your pedal stroke and find your most powerful and efficient orientation. This level of adjustability helps reduce knee stress and maximize output throughout the entire 360-degree rotation.
The Rotor Aldhu connecting rod assembly consists of arms, axle, plates and spider, as well as separators if necessary (axle not included).
