Rotor Aldhu Direct Mount Cranks.
The perfect track crank, combine these with the rotor track spider axle combo
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.
* Chainrings, spider and axle sold separately
