RDhrdNDPUTupWET, noticed in your sig that you ride an '05 Cdale R700. That is another one on my list. It appears to have the same/similar frame as the '04 R800, better components, and my LBS can order it in the slate color I love and throw in $100 in accessories. Do you like the wheels on it?
As for riding, no, I haven't ridden any. The F70 isn't is stock and I haven't had a chance to ride the R800 (its 25 miles away) or the Fuji.
