Well, he measured it wrong. It should be from the center of the bottom bracket (pedal axle) to the center of the top tube...so add 1.5" to 2". I think cyclotoine is probably right...about 54 cm, which may still be too small for you. You say your inseam is 30"? Pants inseam? Riding inseam is different, measured to your pubic bone:

I'm a 32" pantleg inseam, but a 35" riding inseam.
And again, the Cannondale has aggressive geometry, so it will put you in a very forward position, and would look silly with a high stem (been there, done that).
