Rotor Q-Ring Inner Chainring for 4 Bolt Shimano Cranks

Rotor Q-Ring Inner Chainring for 4 Bolt Shimano Cranks brings Rotor's oval chainring technology to your Shimano-compatible drivetrain in a compact inner ring format. The oval profile is designed to work with your natural pedal stroke, reducing resistance through the dead spots of the pedal cycle and increasing power application through the power phase. Available in 36t and 44t options, it fits 4-bolt Shimano cranks and installs as a direct replacement for your existing inner ring. Q-Rings are engineered to deliver a smoother, more efficient pedaling experience — particularly over long rides or sustained climbing efforts where fatigue becomes a factor. Rotor's oval design is intended to ease joint stress while maintaining consistent drivetrain engagement, making this chainring a considered choice for endurance-focused road riders and those managing knee discomfort under load.
