Yes, it is a complete carbon bike including stays. Where I'm uncomfortable is the zertz inserts in the stays which I'm scared will weaken the frame with lateral motion from the Bob. As I said earlier, I'm really not concerned about the strength of the carbon itself. It's a good idea to try it out. I'll see if I can borrow a Bob for a test. Anyone reading in the Boston area have a Bob I can borrow for a test ride?
