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.
CARBON
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.
LIGHTER AND STIFFER
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.
SETTINGS FOR EVERYONE
Never before has a crankset offered so many options to meet the different preferences and needs of each individual cyclist.
Combine the crank arms with different types of spiders, chainrings, and axles. Looking for a power meter? Then choose the INspider, or you can add it in the future; this is one of many advantages of ROTOR cranksets modularity.
UPGRADE YOUR ROAD CRANKSET
If you are already riding one of our ALDHU® or VEGAST® cranksets, their modularity will allow you to easily upgrade to ALDHU® Carbon.
You will only need to purchase the ALDHU® Carbon crank arms since the rest of the components are compatible with our current range of ROTOR road cranksets.
A 10mm hex key and a couple of minutes is all it takes to complete this easy upgrade. Simply unbolt the alloy crank arms, bolt the carbon arms in their place, and head out for a ride.
