ROTOR Direct Mount 1X Road Chainring

The ROTOR Direct Mount 1X Road Chainring offers a one-piece simplified chainring design that saves weight while simultaneously increasing rigidity. The chainring is made from a single piece of aluminum, so rigidity is improved as ROTOR is able to align the aluminum’s unidirectional fibers to maximize strength. In addition, these rings feature ROTOR’s OCP mount technology, which allows you to adjust the oval positioning in one-degree increments in order to fine tune your pedal stroke. The chainring is compatible with ROTOR’s 2INpower and INpower DM power meters as well as the ALDHU 3D+ crankset.



The ROTOR DM 1X Road Chainring is available in the following chainring sizes for both round and Q-Ring:

  • 54 | 52 | 50 | 48 | 46 | 44 | 42 | 40 | 38
