From this chart.. http://www.harobikes.com/2003/geo/ex3geo.html Which size would best be suited for a 6'1" women with beginner skills that does not like to be hit in the vulva area. Do they consider the 19.5 a large or extra large? I've got a trek 21.5 (extra large) and I know she does not like that, its too tall for her liking i.e. hitting the top tube too easily during stand over. I can't figure out if the 19.5 would fit her ok or 17.5? Suggestions? btw, there are no dealers that stock this bike so if I'd order one, it'd be the one she'd(I'd be stuck with) have to keep.
