- Q RINGS options have never been better because drivetrain innovations have never been more diverse.
When SRAM upended standard chainring sizes with its RED eTap AXS 12-speed groupset, ROTOR pivoted quickly on the concept and created compatible oval chainrings.
50/37 and 48/35 Q RINGS combinations with either BCD 110x4 or BCD 107x4 are new standards for SRAM loyalists who want to improve their performance and pedal healthy.
