With adjustability as top priority, we bring the new ROTOR DM 1x Q Ring with OCP mount technology to the forefront for complete control of your chainrings. Combining direct mount and OCP technology seemed to be the most natural progression for the DM Q Ring, we move away from the drastic adjustments found in previous Q-rings, and instead allow you to find the optimal placement in your pedal stroke a single-degree at a time with increments optimized for pedaling biomechanics.
The DM 1x Q Ring features a single meticulously machined chainring that hosts our signature 12.5% ovality constructed to heighten the performance advantages of oval chainrings, without compromising adjustability. This enables cyclists to harness the most powerful portion of their pedal stroke, and alleviate joint pressure and strain through the softest points, finding the optimum placement for the most efficient — and comfortable — pedal strokes ever.
We start by CNC-machining the DM Q Ring 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.
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.
