Why We Like The Aldhu Carbon Crank Arms

First, we like how lightweight the Aldhu Carbon Crank Arms are thanks to their carbon fiber construction. Lighter and modular were the base points for developing the new Aldhu Carbon Crank Arms, and Aldhu completed the project by improving on every aspect of their existing cranks. The brand managed to increase the crank arms' absolute vertical and horizontal stiffness, and it offers versatile options to meet the preferences of individual cyclists.


  • Upgrade your road crankset to a lighter, modular option
  • Versatile setting to set preferences for individual cyclists
  • Crank arms are 100 grams lighter than the aluminum model
  • Increased absolute vertical and horizontal stiffness
  • 30mm crank axle compatible with most BB standards
  • Item #RTR1WUD
