Does anyone know what size bike a 5' 6" woman would normally ride? The guy yesterday told me the 54 was too small for me and that he would see if he could get a 56. Today the shop owner called me and said that for my height a 56 is way too big. He said his wife is 5' 9" and rides the 54. Now I don't know what to think. Is he just trying to sell me the bike he has available or was the other guy wrong? I'm so confused
