ALDHU Carbon Aero 2x12s Crankset

ROTOR ALDHU Carbon Aero 2x12s Crankset. Designed for riders seeking maximum aerodynamic efficiency and performance, this crankset combines ALDHU Carbon crank arms with an integrated Aero MAS spider and aero chainrings to deliver a complete high-performance solution for road and triathlon bikes.

The ALDHU Carbon crank arms are constructed from high-modulus carbon fiber, offering an exceptional stiffness-to-weight ratio while keeping weight to a minimum. Paired with a lightweight aluminum axle, they ensure efficient power transfer and optimal responsiveness under load.

The system integrates the Aero MAS spider (BCD110x4), engineered to improve aerodynamics by reducing drag at the crankset area. Combined with ROTOR 2x aero chainrings, available in both round and QRINGS® oval options, it enhances airflow while maintaining precise and reliable shifting performance for 12-11s drivetrains.

Manufactured from 7075-T6 aluminum and CNC machined, the chainrings deliver outstanding durability, low weight, and high stiffness. The system is fully compatible with Shimano® 2x12s groupsets and designed to meet the demands of competitive road, triathlon, and time trial riders.

Upgrade your bike with the ROTOR ALDHU Carbon Aero 2x12s crankset and benefit from a perfect balance of aerodynamics, lightweight construction, and power efficiency to maximize your performance on every ride.
