So if I decided to get a 47 cm sized frame instead of a 50 cm sized frame.. what is the disadvantage?
A bit small is better than a bit large.
If it feels too cramp, use a longer stem.
My inseam is 74cm and 49cm is my preferred size.
According to BD's sizing chart, the 50cm has a 52cm TT. The 47cm has a 51cm TT.
More likely, a 47cm is a good start for you. Just use a longer stem if it is too cramp.
