I'm 6'4" the current bike has a 100mm stem on it with a set of risers. I like a long low position. Like the old school bum in the air nose on the front wheel.
Lay back post on order? Well you can soon move it on if you can't live with it. I might sell this one later in the year, depending on my back. I vary between 6 1 and 6 2 or 3 depending on how straight my back is!
