Detalles

The ROTOR ALDHU Direct Mount crankset is currently the lightest crankset in the product range of the Spanish bike specialist. Its name is an abbreviation for the legendary Alpe d'Huez stage on the Tour de France, to commemorate ROTOR's first Tour victory in 2008.

With its practical modular design and crank arms trimmed for lightweight construction, the ALDHU impresses with an outstanding balance between low weight and high stiffness. Plus, it can be adapted to almost every frame standard as well as personal preferences, using different axles and chainrings.
Choose your setup from the Road Standard axle for classic road bikes with rim brakes or the Road Offset axle for road bikes with modern disc brakes. In addition, you have the choice between the one-piece oval ROTOR Q-Rings Direct Mount double chainrings, the round ROTOR Round Direct Mount double chainrings or the classic Spider for chainrings with 4 x 110 mm bolt circle diameter.

Direct Mount:
All current ROTOR cranks of the Road Series ALDHU and VEGAST, the MTB series RHAWK , RRAPTOR and KAPIC as well as the powermeters INpower DM and 2INpower DM use the established Direct Mount system for chainring installation. A system that has proven its worth in mountain biking for years. This allows for easy chainring replacement, direct engagement on the axle and maximum flexibility in the choice of gear ratios and drivetrain characteristics. Moreover, the fine toothing between crank and chainring allows you to adjust the oval ROTOR Q rings with 1° accuracy.
