The only frame I can find in a 19 or above (19 is slightly small for me) is a 29er hardtail. The only 26er full suspension bike I found in a 19 (I need a 20 if I am picky) is a DH version, not that great for touring, and approaching $2k in price for something that spec wise is pretty average.

I am easily in the top 1 percent for height (at 6'2) here. And Filipinos approaching my height usually have shorter legs. So it really doesn't pay the bike shops to stock much over 17" bikes.

I've looked for parts bikes (as a donor to a recumbent build), and I'd be better off buying new from the asking prices.
