Rotor Bike Components ALDU Crank Arms 165Rotor is stepping up their game with Aldhu. It is a crank component system, allowing you to not only customize 1x, or 2x, chainrings, but also utilize super light one piece chainring and spider, both in round and Q formats. Here youll find the Aldhu 3D+ Crank Arms. Aldhu is short for Alpe dHuez, which, when youre climbing it, begs for light components, to minimize your drag, and stiff components, to maximize your power.
