Gear ratio is simply (# of ring teeth)/(# of cassette teeth). For example, my highest gear is 53/12 = 4.42 and my lowest gear is 39/25 = 1.56. It is calculated based on the speed and cadence data and it is simply a measure of how many revolutions of the wheel you get for each revolution of the crank.
