The Rotor NoQ DM ALDHU 3D+ chainrings are made of 7075 aluminium. You can only assemble these chainrings to a Rotor ALDHU 30+ crankset. This combination of chainrings saves up to 30 grams compared to a normal spider with loose chainrings. The Rotor NoQ DM ALDHU 30+ chainrings are, therefore, the ultimate combination to make your ROTOR ALDHU 30+ crankset complete.
