I have the same problem, I have tried different skewers, under a lot stress the wheels slips left and rubs against the frame. I believe that the dropout is worn, I don't know if aligning the dropout will help. It's a carbon bike. A mechanic told me the frame is crooked. I am going to work with my LBS and see what Cervelo thinks.
