ALDHU® is our lightest crankset ever at 599 g and the name is an abbreviation of the mythical Alpe d`Huez stage on the Tour de France to commemorate ROTOR ́s first iconic victory with Carlos Sastre in 2008
Combined with our one-piece chainrings that are machine CNC’d from single blocks of aluminum you can enjoy the perfect balance between lightweight and stiffness.
Our new one-piece Round Direct Mount chainrings are machine CNC’d from single blocks of ultralight aeronautic-grade 7075 aluminum and can be mounted straight onto the axle or crank arm. With fewer individual parts we’ve shaved precious grams off the component weight and focused on delivering you ease of assembly and maintenance. The integrated configuration means a simplified lightweight solution without compromising on durability.
Comes with 24mm axle would fit a Shimano Hollowtech 2 Bottom Bracket
