Rotor Crank Axles ALDHU Carbon Chain Line

With the ALDHU Carbon, ROTOR is bringing the lightest crank in its company history onto the market. The name is an abbreviation for the legendary Tour de France climb of Alpe d'Huez, where Carlos Sastre laid the foundation for overall Tour victory in 2008 with Rotor Q-Rings, thereby giving ROTOR one of the greatest victories in the company's history.

The ALDHU crank system has a modular structure for the greatest possible adaptability. The chain line for disc and rim brake hubs can be adjusted using 2 different shafts and the 110-millimeter 4-hole spider can be exchanged for ROTOR's direct mount chainring combinations. For the optimal adjustment of the oval ROTOR Q-Rings chainrings, the OCP system (Optimum Chainring Position) has been further refined. The position of the chainrings can be adjusted in 1-degree increments using a combination of different positions of the crank arms on the crankshaft and a fine-grid spider mount. All you need to adjust and install the chainrings and crank is a 10-millimetre hexagonal wrench.
