Suspension seatposts reduce vibrations caused by uneven
roads thereby reducing stress on the spinal column.
If you need to adjust the suspension elements in the seat-
post, consult your specialist cycle shop.

9.3 Adjusting the handlebar position
Tighten all screws to the prescribed torque as other-
wise screws could shear o and components could
come loose or detach altogether (see
Chapter 30
"Technical data").
You can also inuence your riding position by changing
the handlebar height.
The lower you set the handlebar, the rther you will have
to lean forwards. This increases the strain on your wrists,
arms and upper body and you will need to bend your back
rther.
The higher the handlebar is, the more upright your riding
position will be. This increases the stress on your spinal
column due to jolting.
You can determine a handlebar height that best suits your
body size as follows:
Sit on the bike saddle.
Ask another person to hold the bike steady if
required.
Bend your upper body towards the handlebar until
you have found a position that is comfortable for
your back.
Stretch out your arms towards the handlebar.
Note the approximate position of your hands and
set the handlebar at this height.
9.3.1 Adjusting / aligning the handlebar
height with a conventional handlebar
stem
To release the stem sha in the head tube, proceed as
follows:
Release the stem expander bolt to loosen the han-
dlebar stem. Turn it anticlockwise by two or three
revolutions using an Allen key.
Clamp the ont wheel between your legs to pre-
vent the bike fork om turning with the stem sha.
Holding the handlebar by the handles, turn it om
right to le and vice-versa.
If it is not possible to do this, tap lightly on the
stem expander bolt with a plastic hammer to loos-
en the clamping xture inside the stem.
Set the handlebar stem to the required height.
Align the handlebar so that it is exactly at right
angles to the ont wheel.
To secure the stem sha again, turn the stem ex-
pander bolt clockwise using an Allen key until it is
tight (see
Chapter 30 "Technical data").
