I've noticed that a lot of pros have bad bike fits, mostly it goes along the lines of too long/too low for their flexibility. Here's a few that stand out for me.
Carlos Sastre - He always seems to hold his bars behind the brake levers, a cm shorter stem would do a lot for him
Alessandro Ballan - Homeboy runs some serious drop, it looks way painful to me, but on the other hand he does keep a nice flat back.
Lance Armstrong - That hump is just scary.
Feel free to add more.
