Still getting more individualised: the ALDHU 3D+ crankarms by Rotor

The ALDHU 3D+ cranks are Rotos’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 model name comes directly 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.

Technology:
Alu 7055
To build the best cranks, Rotor starts with the best materials. 7055 combines the superior physical properties of a 7000 alloy series with incredible fatigue resistance. Every single bar of raw material is checked by ultrasonic inspection to guarantee it free of internal defects. 7055 is used to craft Rotor’s 100 % CNC-machined cranks, like the FLOW, the 3D+, and the REX 1.

Alu CNC
Manufactured with the latest technology. 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 functionality 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.

TDS
Rotor´s CNC-machined cranks feature the Trinity Drilling System, which is a process that drills three full-depth holes along the axis of the crank. This allows them to remove excess material from the crankarm resulting in a lighter crank without compromising its exceptional stiffness-to-weight ratio.

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.
