ROTOR Direct Mount Road Chainring
The ROTOR Direct Mount Road 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 Road Chainring is approximately 30 grams lighter by comparison. In addition, because the ring is made from a single piece of aluminum, rigidity is improved. ROTOR is able to align the aluminum’s unidirectional fibers to maximize strength. The Round option of these chainrings use ROTOR’s latest Universal Tooth technology, making them compatible with any chain. This includes SRAM and Shimano 12-speed. These chainrings are compatible with ROTOR’s 2INpower and INpower DM power meters as well as ALDHU, VEGAST and QO RACE cranksets.
Options
The ROTOR DM Road Chainring is available in the following options:
- Round Universal Tooth: 48/31T | 50/34T | 52/36T
- Q-Ring Oval: 50/34T | 52/36T | 53/39T
Compatibility

- Chain: The Round Universal Tooth chainrings are compatible with any chain, including Shimano 12-Speed and SRAM 12-Speed Flattop. The Q-Ring version is compatible with 9-, 10-, 11-speed chains, along with 12-speed Shimano. The Q-Ring version here is not compatible with SRAM 12-speed Flattop.
