Details

Q-Rings improve your performance by varying the resistance when pedalling according to the natural strengths and weaknesses of your legs. More stress is put on stronger muscle groups to increase the positive physical effort. The weaker phase of the pedalling cycle is compensated simultaneously. Q-Rings improve thus the pedal stroke thanks to 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. You can mount the Q-Rings chainring to optimise the sequence of movements in 5 different positions.
