Pablo is wise!

I'm 6'3" and have ridden frames from 19-21" I am also more body than legs, 34" inseam. So a longer top tube helps me out. The best way is to ride several bikes for at least 30 minutes on trails. See what set up works best. Pay attention to things like hands and feet tingling. There are so many important things to choosing a bike. If it doesn't feel good on rides it will end up collecting dust.
