Rotor QX2 Sram XX BCD 120 Outer Chainring

If your bike reflects your identity as a mountain biker, then selectivity and brand loyalty marks your choices. For SRAM cranks requiring a specific BCD, we crafted special 120/80BCD QX2 rings for your SRAM 2x cranks. In addition to biomechanical performance, we wanted everyone to experience Q-Rings – QX2 rings with 120BCD provide all the performance benefits of standard QX2´s while accommodating proprietary spider designs. The QX2´s feature a subtle 10% ovality and offer 3 Optimum Chainring Positions (OCP), which 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.
