By increasing your gear when you are strongest, and reducing it at the dead spots Q-rings make your spin cycle smoother, make climbing easier on the arms and helps reduce the build up of lactates during hard efforts.  

Rotor Q-Rings minimize the dead spots like reducing the size of a regular chainring, and give you more time during power stroke. This allows for a lower physical demand on your body, so you are able to ride longer with less fatigue, climb easier...
