So almost 60cm for the top tube, that's a good lenght.
Although his photos said around 57 which is no good for me but that's probably a proper size for a 20" frame.
My 22" Trek 990 has 59cm and my Terrarunner at 57cm C-T (22.5") is 59.5.
It's not going to be used as an MTB, does anyone know what...
