Thanks for your responses so far.
My wife helped measure my inseam and we figured it to be around 31 cm. But that number seems low as a chart I looked at on one website said that a person who is 6 feet would have an inseam of 34cm and the frame size should be 58 to 59 cm. It seems so confusing. I am finding people have different opinions. A person who works in a bike shop and is in my university class says that I should have a 19" or 50cm frame, but that seems too small.
This frame I am looking for will be a road frame.
