The seat's part of the problem. The handlebars are the other part.
Try dropping the seat a full cm and angling it up, maybe? If the saddle's pretty far up on the rails then that +/- angle can pretty easily be a full cm.
I'll leave that but I was tempted to delete it. It may work, but there's no way to know without seeing you ride.
