Intermediate Gears

sophidog

got a Cannondale CAADX last sept & i know that the cassette is a 11-25; anyone know what the numbers are between the two please? I trying to calculate the 'inches per pedal revolution' but i can't see anything on Shimano's or Cannondale's sites. I know they've changed the gearing on the 2012 model but i got the 'old' 2011 version. TIA :?:

The tooth counts are stamped on the outer face of each sprocket. You might need to give them a good clean though...

Alternatively, count the teeth.
