|Is it a disadvantage to have a small frame, like a 50cm frame, compared to a 56cm frame? Doews the geometry change drastically, whats the difference?|

|If a 56cm frame is your size, it makes a huge difference. First of all, the top tube will be way too short. Second, your handle bars will be very low compared to your seat height.|

|The short answer is that just like buying a new suit or shoes, the correct size bike frame is important. The correct size bike to fit you will vary from brand to brand.
Bigger bike frames are bigger all over. Besides being taller, they are also longer. Bigger bike frames also usually have different head tube and seat tube angles to adjust for different body porportions.
Many newer bikes use "compact geometry" in which a 50cm frame may well equate to another manufacturer's 56cm frame. You shouldn't assume that all 50cm frames, even traditionally porportioned frames, are the same size.
The bottom line is that the frame size number is only moderately useful. You need a bike whose handling, feeling and looks appeal to you. To get this there is no substitute for the help of a skilled salesperson and actually riding the bike.
