Holy cow! 4 inches behind? That's a good setup for a beach cruiser. How much weight do you need to get off your hands? A good road bike setup is all about a good balance between weight fore and aft. One problem with being so far behind is that no matter what you do with your handlebars, you will have to bend over too sharply at the waist to ride comfortably, plus, you will have so much of your weight on your behind that anything you gain for your hands you will lose for your butt. You have to take these things you read about having the saddle all the way back with a grain of salt.
