Description
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 speed if it is optimally adjusted. The wheel stays
in contact with the ground when passing over
bumps (blue line). The fork head, handlebars and
body follow terrain (green line) when riding over
bumps. The suspension motion is predictable and
controlled.
Figure 18: Optimum fork ride performance
When optimally adjusted, the fork counteracts
deflection on hilly terrain and stays higher in its deflection range. This allows the rider to maintain
the same speed more easily on hilly terrain.
Figure 19: Optimum fork ride performance on hilly terrain
When optimally adjusted, the fork deflects quickly
and unhindered when the bike hits bumps and
absorbs a bump. Traction is retained (blue line). The fork responds quickly to the bump. The
headset and handlebars rise slightly when
absorbing a bump (green line).
