Oval isn't for everyone.
Rotor is known for its ovalized chainrings, yet some riders still like the feel of traditional non-oval rings. To "round" out its quiver of road and mountain rings, Rotor has added a series of mountain bike-compatible rings. The RX1 is designed for the new 1x drivetrains.
These round rings are designed identical to Rotor's Q-rings, save the ovalized shaping. They were CNC machined from 7075-T6 aluminum and feature stainless steel pins. Used with the appropriate spider, which is sold separately, they are compatible with SRAM, Rotor REX, and Specialized 1x crank arms.
The Rotor RX1 Chainring comes in etched Black and in a 32t configuration.
