Errr, if I were you, I would not want to be responsible for putting my friend and his money onto a full-blown racing bike or racing bike replica. There's more to it than handlebar height, but if that is important, I can guarantee you that unless your friend intends to eventually use the bike in professional road racing, he will be able to set his handlebars as high or as low as needed by any serious recreational road bike rider. Just make sure he doesn't pick a frame that's too large or too small.
