Rotor Aldhu 3D+ 24mm crankset axle

Rotor’s lightest crankset ever, the Aldhu's innovative modular structure makes each component individually available to accommodate the current spectrum of riders and bike standards. Aldhu axles independent of the crank arms enable the user to build a crankset unique to his or her bike set up. The Aldhu incorporates OCP Mount technology, which enables the rider to fine-tune the orientation of Rotor’s oval Q rings. The Aldhu’s proprietary, patent-pending design is based on the modularity of each crankset component. The new model name comes from an abbreviation of Alpe d’Huez to commemorate Rotor’s first iconic victory at the Tour de France with Carlos Sastre.

Technologies

ALUCNC
Computer Numerical Control (CNC) machining provides a precise and consistent manufacturing process. This is especially important when it comes to crafting bike components in order to ensure flawless funcionality with respect to all the parts working together. Equipped with the latest CNC resources, Rotor parts are precisely machined to within a hundredth of a millimeter.

Twin leg
Rotor’s Twin Leg Concept boasts the stiffest possible crankset by balancing the cranks’ left-to-right stiffness. There is no point in making an ultra-stiff right crank arm if the left crank arm doesn’t measure up. By designing the cranks as a real set — not just two individual arms, TLC offers the most-balanced cranks possible.

OCP mount
Rotor’s exclusive patented technology “OCP Mount” refers to the pedalling’s biomechanical optimization when you are using Q rings or other oval chainrings; this lets you adjust the orientation between chainrings and cranks by one step degree.
The shape of the axle lets you position independently both cranks and spider or Direct Mount, and thereby change the relative orientation in order to adapt to the optimum orientation of each user.
