frame angles

Usually shown on the frame or bicycle geometry chart (or found by measuring), frame angles help you understand a bicycle's riding characteristics. The angles used are the head-tube and seat-tube angles expressed in degrees. So, for example, a road bike might have a 74-degree head tube and a 73-degree seat tube. As a broad, general rule, as the angles steepen the ride stiffens and vice versa.
