There’s no need to swap out your Shimano XTR cranks to accommodate our QX rings for your mountain bike, ROTOR has crafted QX2´s with a 96/64BCD just for you. In addition to biomechanical performance, there was one more important factor when designing our Q-Rings: compatibility. We wanted everyone to be able to ride Q-Rings so we designed special Q´s for cranks requiring a specific bolt pattern. QX2 96/64BCD for your XTR cranks 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.
