The most sophisticated crankset technology we’ve ever developed

Intrinsically clever design, beautifully elegant finish

Endeavor to improve

Our 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 we set about creating our new ALDHU 3D+ crankset, we poured all the knowledge and effort from our professional athletes and expert engineers into producing our 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 3D+ 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, our 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 our lightest crankset ever at 599 g. 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

We take meticulous care when crafting our ALDHU 3D+ crank arms using aeronautic-grade 7055 aluminum. The sophisticated 3D+ 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. We’ve created our most advanced crankset ever so you can conquer the most prestigious and steepest of climbs.
