Q-rings improve the pedal stroke thanks to the reduction of the dead spot. This allows you to ride upright longer while climbing and reduces fatigue of the muscles. Besides, the cardiovascular endurance (endurance of heart and lungs) is improved. The x4 version fits the new Shimano 4-arm road bike cranks such as Dura Ace FC-9000, Ultegra FC-6800 and 105 FC-5800.
