I have a 1990 Trek 720 and the 23" is too small for me at 6'6".
I did the same as
veganbikes and made my own out of a New Albion Privateer. The 23" Trek is now up for sale.
Hi, you've a couple inches north of this guy and it is certainly true - an XXL is a better choice for 6'4" and up. I'd found the bike I'd been looking for for years but it was
only an XL. Too bad. I haven't called the company to ask how many XXL they had made (they did make them) but probably should. Some companies tend to be conservative in their sizing, but not Rocky Mountain. The 720 you've got there would
just fit, assuming a 23" top tube. I had a 1987 raleigh elkhorn mountain bike with similar square dimensions (23/23) that worked fine, this assumes an older hybrid and an older mountain bike would have similar geometrys.
