Rotor ALDHU 3D+ Crankarms - black

Introducing the new ALDHU 3D+ cranks, ROTOR’s lightest cranks ever. The innovative modular structure, together with axles and different chainring options, makes each component individually available to accommodate the current spectrum of riders and bike standards.

The ALDHU 3D+ incorporates OCP Mount technology, which enables the rider to fine-tune the orientation of ROTOR’s oval Q-Rings. The ALDHU 3D+’s proprietary, patent-pending design is based on the modularity of each crankset component.

The models name is directly derived from ROTOR's 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.

The crank arms of the Rotor 3D30 are made of CNC machined and forged 7055 aluminium which have been trinity drilled for a further weight reduction. Rotors axle systems has been specifically developed for multiple BB systems. In addition Rotor has extended the compatibility of the 3D30 because now it's equipped with an improved ultra stiff 30mm aluminium UBB axle.

This crank is manufactured using an improved version of RotorŽs proprietary "Trinity Drilling System" technology during manufacture. Due to the larger axle-crank contact area of a BB30 crank, all three holes can be drilled from the axle side of the crank arm, allowing further optimization of wall thicknesses. It improves both the weight and the weight-rigidity ratio of the crank arm.
