How do Q-Rings work?
Q-Rings reduce dead-spot negative effects due to its effective variable gear oval concept. The effective gear is lower at the dead-spot zone, so it is easier, faster and more comfortable (smoother) to pass through it. Once the pedal is over the dead-spot and enters the down stroke, the Q-Rings progressively increase the effective tooth size as more muscle strength is available.
