With adjustability as top priority, we bring the new ROTOR DM Oval Chainring 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 Oval Chainring, moving away from the drastic adjustments in previous oval chainrings, and instead allowing you to find the optimal placement in your pedal stroke a single-degree at a time with increments optimized for pedaling biomechanics.
The DM Oval Chainring features two meticulously machined chainrings that host 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 Oval 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.
