3.3.6.2 Suspension seat post
Suspension seat posts can reduce shock after
one-time hard impacts, thus improving ride
comfort significantly. However, suspension seat
posts are not able to compensate for bumps in the
road.
If the seat post is the only suspension element,
the entire pedelec is a non-suspended mass. This
has an unfavourable effect on loaded touring
bikes or pedelecs with child trailers.
Suspension seat posts feature small, heavy-duty
slide bearings, guides and articulated joints. If
they are not lubricated on a regular basis, the
sensitive response behaviour diminishes
considerably, causing excessive wear.
The pre-tensioning in non-damped suspension
seat posts must be adjusted in such a way that the
suspension seat post does not deflect with just
body weight. This prevents the suspension seat
post from deflecting and bobbing intermittently at
higher pedalling frequencies or if the rider pedals
irregularly.
The spring stiffness can be set lower with damped
suspension seat posts, thus making use of the
negative deflection.
