I have a friend who is 6'5" who rides a vintage Panasonic 27" frame. He needs the height to get the bars high enough to ride comfortably. The stem and seatpost he would need to use on a 58 or even 60 cm bike would be really long, and the reach would not be there on such a bike. He wanted to buy something new or newish this season but in the end, he couldn't find something with the same or similar geometry to his old Panasonic unless he went with something custom or semi custom and that was out of his price range, so he just decided to stick with what he has.
