Description
Negative deflection (sag)
The negative deflection (sag) is the percentage of
entire deflection that is compressed by the rider’s
body weight, including equipment (such as a
backpack), the seating 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).
