ROTOR Direct Mount MTB Chainring

The ROTOR Direct Mount MTB Chainring offers a one-piece simplified chainring design that saves weight while simultaneously increasing rigidity. Compared to a standard chainring with spider and bolts, the ROTOR DM MTB Chainring is approximately 40 grams lighter by comparison. In addition, because the ring is made from a single piece of aluminum, rigidity is improved as ROTOR is able to align the aluminum’s unidirectional fibers to maximize strength. The chainring is compatible with ROTOR’s 2INpower and INpower MTB power meters, RHAWK and RRAPTOR cranksets and works with all 9, 10, 11, 12 and 13 speed groupsets.



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

  • 38 | 36 | 34 | 32 | 30 | 28 | 26
