Rotor Shimano 4 Bolt Q Rings Ultegra / Dura-Ace 52/36t
The ovalised shape of the 52/36t Rotor 4 Bolt Q Rings for Shimano Ultegra / Dura-Ace cranks provides greater efficiency throughout the pedal stroke for more power and less fatigue. They achieve this by evening out the power, reducing the strain during the weaker phase and increasing resistance through the stronger area of the rotation. Shifting between the rings is slick and crisp thanks to the sculpted ramps and pins that help move the chain up or down accurately, even when under maximum pressure.
