A 30mm axle make the crankset stiffer and lighter. A low Qfactor of 140mm ensure a perfect position in the bicycle for TRACK and Fixed users. * Chainrings and cranks sold separately
Settings for everyone
Never has a crankset - like the ALDHU® Carbon crank- offered such wide configurations to meet the different preferences / needs of each individual cyclist.
Combine the cranks arms with different types of spiders, chainrings and axles. Looking for a power meter? Then choose the INspider, or you can also add it in the future; this is the main advantage of the the modularity of ROTOR cranksets.
In short, a solution that will adapt to your needs without having to replace the complete set.

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.
Crafted through technology
We take meticulous care when crafting our 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.
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.
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.
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.
