When a clean and fuss-free setup is your top priority, messy two-by setups and front derailleurs just get in the way. That's why we've crafted the ROTOR DM 1x Round Ring for road. This clean and simple ring cleans up your drivetrain, allowing you to pick the optimal gearing for your ride, whether you're hunting down a 38-tooth chainring for endurance rides or a lofty 54-tooth for your Ironman.
The DM 1x Round Ring features a single precisely machined chainring. We craft it by CNC-machining the chainring from a single block of aeronautic-grade 7075 aluminum to shed every unnecessary gram while harnessing stiffness and durability. Meticulous attention to detail keeps the tolerances tight, so chain retention stays snug, and shifts feel deliberate and precise.
