Our new Cinch Direct Mount Oval rings help you put down the watts in the best part of our pedal stroke. Ovals provide enhanced traction control when compared to conventional round rings, particularly in high torque, low cadence riding scenarios. We arrived at an optimal 10% ovality and 112.5° clocking, which can be achieved in both regular and flipped Super Boost positions by following the orientation callout on the rings. Our variable width tooth design will keep chain retention dialed utilizing clutched derailleurs, and is also compatible with many chainguides.
