Stand Over Height and Seat Tube Angle

The stand over refers to the height of the tube that holds the seat pole. This height determines the height of the top tube in relation to the angle of the headtube. As trends have changed over the years companies have experimented with very low (6.5") standover heights whereas other brands have gone the other way making standover heights at 9.5". The angle of the seat tube does change the feel of the bike. This is why it is important to take note of both the height of the tube with the angle of the tube. Most frames have a common angle of 71 where some lean a little lower with a 69-70 degree seat tube angle.
