dumb caad question: for the caad9 (and presumably the 10), whats the stock stem lengths on a 58 vs a 60? I know Cannondale "sizes down," so a "58" is really 56(st) x 57.5 (virtual tt), and a "60" is really 58 (st) x 59 (virtual tt).
If it comes down to me having to order in a 10 in my size to try it, sight unseen and off of spec sheets, I'd like to get as close as possible to dialing in the reach the first time around... (and also save my LBS the worst case scenario/hassle of having to order in a second one, and deal with the one I don't like)
