No, but I did just check the bike and the seat tube does measure 61cm from the middle of the bottom bracket to the middle of the top tube.

Maybe the 60cm won't be overly small after all.

Edit: I just read that Cannondale measures the frame sizes from the middle of the bottom bracket to the top of the top tube. In that case, my current bike measures out to what looks like 62.5cm, which is I guess close enough to make it a 63cm.

So now I'm back to thinking that a 60cm will be on the small side.
