Product Description

ALDHU® Carbon features ROTOR’s innovative modular design with OCP Mount for Q RINGS® and Direct Mount technologies. Combined with our 1x or 2x DM chainrings that are machine CNC’d from single blocks of aluminum you can enjoy the perfect balance between lightweight and stiffness.


Lighter, modular, and made of carbon fiber

These were the targets for developing the new ALDHU® Carbon cranks. The most loyal fans of our brand had been demanding a carbon crankset for years. ROTOR accepted the challenge with a single goal: We had to improve on every aspect of our existing cranks.


We all know that the introduction of disc brakes to road cycling has increased the weight of bicycles.

Our goal was to reduce some of the weight increase, but without sacrificing the stiffness of our cranks.

The result? Crank arms that are 100 grams lighter than the ALDHU® aluminum model, leaving the total weight at only 523.5 grams (172.5 mm & 50/34t DM chainrings). At the same time, we managed to increase its absolute vertical and horizontal stiffness by 11% and 36.1% respectively.
