Rotor Aldhu Carbon Crank For Road/Gravel Bike Crank Armset with axle

Introducing ROTOR’s first ever carbon crankset! The ROTOR ALDHU Carbon Road Crank Arms are crazy light, weighing 100 grams less than the ALDHU aluminum model. In addition, vertical and horizontal stiffness had been increased by 11% and 36%, respectively. The Carbon ALDHU also features the same modular design so you can use it with any ROTOR 1x or 2x DM chainrings. It is also compatible with the ROTOR INspider and power2max ALDHU power meters.

This crankset uses a 30 mm spindle and can be run with both 1x and 2x chainrings. This is also compatible with 110×4 BCD and 110×5 BCD chainrings.

ROTOR manufactures a Standard and Offset axle that are both compatible with this crankset. For most road and gravel bikes, the standard axle provides the correct chainline. For riders using a GRX drivetrain or gravel bikes with a 50c or larger tire clearance, we recommend the Offset axle.

Carbon construction, multiple crank length options, versatile drivetrain options and ROTOR INspider power meter compatible.

This is a great crankset for road and gravel riders looking for an ultralight and stiff carbon crankset. It addition, you can run it in a number of configurations.

Power meters and chainrings: This crankset is compatible with the ROTOR INspider Power Meter, power2max ALDHU Power Meter, as well as ROTOR chainrings.

Bottom bracket: These cranks fit 30 mm road bottom brackets.
