Overview
Negative deflection
Sag is the percentage of total deflection that is
compressed by the rider's weight, including
equipment (such as a backpack), their seating
position and frame geometry. Sag is not caused
by riding.
The S 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 rider broadly follow
the terrain (green line) when riding over bumps.
The suspension motion is predictable and
controlled.
Figure 4: Optimum fork riding performance
When optimally adjusted, the fork counteracts
deflection, stays higher in its deflection range and
helps the rider to maintain speed while riding on
hilly parts of terrain.
Figure 5: Optimum fork riding 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).
