CNC-machined from a single block of 7075-aeronautic-grade aluminum, we built the ROTOR DM Round Chainrings to shed weight left and right, while maintaining total rigidity and durability for the long road ahead. By utilizing top-tier materials, and a construction that drops every unnecessary nut and bolt,we were able to knock more than 30-grams off of the weight of standard chainring combos topartner with ALDHU crank arms, taking the cake asourlightest crankset ever.

With some help from ALDHU 3D+’s innovative modular structure,we areable to make each component of the crankset individually available to accommodate the current spectrum of riders, and bike standards.
