The ROTOR Q-Ring DM Singlespeed SRAM GXP & BB30 – BOOST – 3 mm OFFSET

In addition to biomechanical performance, there was one more important factor when designing our Q rings: compatibility. New Direct Mount Q rings allow you to upgrade your SRAM GXP crankset to go oval. The simplified one-piece design saves approximately 40 grams compared to standard ring+spider+bolts combination (for example, weight savings for a 32t ring is 40g). Direct Mount oval chainrings for SRAM GXP can be dialed in to take advantage of the most-powerful part of your pedal stroke to give you faster acceleration and better traction when you need it most.
