Description
Sag
The
Sag (
negative deflection
)
is the percentage
of total
shock travel
that is compressed by body
weight, including equipment (such as a
backpack), the seating position and frame
geometry. Sag is not caused by riding. The
ebike
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 8: Optimum fork riding performance
When optimally adjusted, the fork counteracts
deflection on hilly terrain and stays higher in its
deflection range. This makes it easier to maintain
speed when riding over hilly sections of terrain.
Figure 9: Optimum fork riding performance on hilly terrain
When optimally adjusted, the fork
travels
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).
