Lock
The compression can be disabled in any
suspension fork. A suspension fork will then
behave like a rigid fork.
A suspension system is designed to cushion and
compensate for unevenness on a surface whether
the user is riding on bumpy cycle paths, dirt roads
or off road. A suspension system absorbs great
deal of motor and muscle power during rides uphill
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.
Figure 15: Optimum suspension fork ride performance
When optimally adjusted, the suspension fork
counteracts deflection on hilly terrain and remains
higher in its deflection range.

The suspension fork also deflect quickly and
unhindered when hitting bumps and cushions the
bump when placed at an optimum setting.
Traction is retained (blue line). The suspension
fork responds instantly to the impact.

or on optimally tarmacked roads. This increases
energy consumption and reduces propulsion. It
thus makes sense to lock the suspension on
tarmacked roads and when riding uphill.
Some suspension forks thus feature a lockout on
the fork crown or a remote lockout on the
handlebars.
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.
This allows the rider to maintain the same speed
more easily on hilly terrain.
The headset and handlebars rise slightly when
absorbing a bump (green line).
