Rotor ALDHU Crank Arms
Rotor's new, highly sophisticated crankset technology has a sophisticated design and its clean aesthetics will complement any setup. The Rotor ALDHU Crank Arms are their lightest to date, engineered from CNC'd 7075 aluminium, with the complete set up weighing around 30 grams less than a standard spider and chainring combination. This process drills three full-depth holes from axle to pedal and results in a crankset that is both extremely rigid and has an exceptional stiffness to weight ratio.
In a collaboration between professional cyclists and engineers, a system has been produced that allows you to fine-tune and optimise your pedalling performance according to your biomechanics, for the highest power outputs at the ideal point of your pedal stroke. The Q-Rings can be adjusted in 1-degree increments to find the OCP (Optimum Chainring Position) for enhanced customisation.
Being a modular system, it's easy to replace individual parts as they wear, or when you want to upgrade. An abbreviation of Alpe d'Huez, the ALDHU system was created to be Rotor's most advanced crankset, and one that'll get you up the steepest mountains.
