THE MOST SOPHISTICATED CRANKSET TECHNOLOGY EVER DEVELOPED BY ROTOR
Intrinsically clever design, beautifully elegant finish
Endeavor to improve
Rotor's DNA is built on the principle of innovative drive train development for the universal benefit of cyclists from world champions to aspiring aficionados.
So, when Rotor sets about creating the new ALDHU® crankset, they poured all the knowledge and effort from their professional athletes and expert engineers into producing their most advanced and complete crankset ever.
Fine-tuned pedalling with scientific precision
OCP Mount’s patent-pending, proprietary technology allows you to precisely adjust your optimal chainring position to within one degree increments. ALDHU® responds to your individual biomechanics allowing you to configure your unique OCP (Optimum Chainring Position) so that your maximum power transfer is activated at the most optimized point of your pedal stroke.
Modularity to build your bike your way
With the flexibility to satisfy the most comprehensive range of bike sizes and standards, the innovative modular structure empowers you to select each crank component based on your unique bike setup and physical characteristics. The spider, chainring and all other components can also be purchased and assembled separately so you can replace individual parts as you upgrade your bike without having to exchange the entire unit.
Lightweight but up to the challenge
The integrated configuration of the one-piece oval direct mount chainrings resulted in the Rotor lightest crankset ever. Machine CNC’d from single blocks of aluminum means a reduced number of parts for easier maintenance and increased durability without compromising on stiffness.
Crafted through technology
Rotor takes meticulous care when crafting the ALDHU® crank arms using aeronautic-grade 7055 aluminum. The sophisticated CNC process drills three full-depth holes from axle to pedal employs micro structural engineering technologies. The result is a crankset with superior rigidity and an exceptional stiffness to weight ratio that can handle anything you can throw at them on the toughest of rides.
Steeped in racing heritage
ALDHU® is an abbreviation of the mythical Alpe d`Huez stage on the Tour de France to commemorate ROTOR ́s first iconic victory with Carlos Sastre in 2008. Rotor has created their most advanced crankset ever so you can conquer the most prestigious and steepest of climbs.
