Improve your performance by using oval chainrings! Oval chainring with 10% ovality. The Q-ring has the largest diameter at the point of the greatest force output, the smallest diameter is at the upper dead center. In addition to biomechanical performance, there was another important factor in the development of Q-rings: compatibility. The simplified one-piece design saves about 40 grams compared to standard Q-rings + spider + screw set. The new Direct Mount Q-rings give users of SRAM GXP Offset cranksets the option of switching to oval rings directly. Available in 30, 32, 34 and 36 teeth, standard chainline and OCP3 position.
