In the interview Cav gave he copped to getting stuck behind Renshaw.
"The thing is that [Soren] Kragh Andersen came in and pushed me out of [Mark] Renshaw's wheel, and it was better to go on his wheel than be in the wind. So I thought, 'OK, he'll go', then he started to go round Renshaw, then Renshaw started to lead out, and I thought the left would be closed, so he came over the right and the gap opened on the left.
"Quick-Step went on the left, and I'm blocked by my own lead-out man. That's going to look shit on paper, but you know what I mean. It was my own fault, I shouldn't have really been there. It's luck of the draw, but like I said, it was going to be hard to beat [Quick-Step]. They've got another stage win, and I'm left holding a baby."
