Did you ride your friends CAAD10? If so what size was it and did you like or dislike anything about the ride?

On that oversize Bianchi PIsta with the seat lowered, your bar drop from the saddle was probably not very much. On a properly sized CAAD of any model, you will have a lot of saddle to bar drop.

Fixing such really isn't as simple as raising the bars. That will make the sexy looking CAAD look like a clown. So figure out if you really want the aero position a CAAD will give you. Otherwise you should look at bikes with a higher stack that won't be as aggressive with the position they give. Cannondale and other bike brands have models of bikes that are made to give you different positions without having to put steerer tube extenders on them or weirdly angled stems.
