So I'm thinking about getting either a Caad 9 or 10 frame used and building it up using parts from my "beater" bike. I currently race on a Supersix but am getting a little nervous about using it all the time after having crashed it a couple times in races this year. I know the Caad 10's geometry is identical to the Supersix, but is the Caad 9 also? It's no longer posted on Cannondale's website. Also anyone ridden both a Caad 9 and 10? Any preference? I know the 10's have bigger tubes, are they noticeably stiffer?

Thanks.

Btw, wan't sure if this would just get buried in the "Cult of Caad" thread which seems to be full of gratuitous pictures more than discussions these days...
