ALDHU Carbon Crank Arms

Lighter,modular and Carbon made!
These were the premises for developing the new ALDHU® Carbon cranks.

The most loyal fans of the brand had been demanding a carbon crankset for years and ROTOR accepted the challenge with a single goal: they had to improve in all aspects what we had manufactured to date.

After more than 4 years of development with a material that until recently we looked at from a distance, this goal has come true.

ALDHU® Carbon crankset come to make the ROTOR history bigger.

Result? Crank arms 100 gr. lighter than ALDHU® aluminum model, leaving the total weight at only 523.5 gr (172.5 mm & 50/34t DM).

At the same time, we can increase its absolute stiffness by 11% vertical and 36.1% horizontal.
