I'm trying to get a better understanding of the differences of these bikes:

- 2011 Quick 4
- 2011 Quick CX4
- 2010 Bad Boy

The LBS that carry Cannondale don't stock all 3 of these, so I haven't been able to ride them all yet. They either carry the Quick 4 or they carry the Bad Boy (so it seems). I've been to a few bike stores to test ride others already, but wanted to understand the different uses of them. I already rode the 2010 Quick 4 (but didn't like it because of the SRAM components), the 2011 has shimano. I'd compare these Cannondales to the 2011 Trek 7.3 and the 2011 Specialized Sirrus Elite.

I'm looking for a bike that I can ride on paved roads, a little dirt paths, etc. To me (a newbie) they seem pretty similiar, is the Quick more geared towards a road bike and the others offer more flexibility? just not sure what the major differences are. I would have to go about 1 hour away to test ride the Bad Boy and CX4.
