Negative deflection (sag)
Negative deflection (sag) is the percentage of
total deflection that is compressed by body
weight, including equipment (such as a
backpack), the riding position and frame
geometry. Sag occurs whether you are actually
riding or not. The pedelec rebounds at a controlled

When optimally adjusted, the fork deflects quickly

the same speed more easily on hilly terrain.
The fork responds quickly to the bump. The
headset and handlebars rise slightly when
absorbing a bump (green line).
