The top tube is measured center to center and is an accurate measurement. The seat tube is measured center of bb to the center of the top tube. notice that the seattube extends above the top tube a few cm's. that's why the given Size of an IRO, and the seattube measurement, are off from each other by a few cm's. i'd suggest paying less attention to the actual seattube measurement, and more attention to the given Size, if you're trying to figure out what fits ya. does that clear things up?
