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 off and components could
come loose or detach altogether (see
➠
).
You can also influence your riding position by changing
the handlebar height.
The lower you set the handlebar, the further 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
further.
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 shaft 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 front wheel between your legs to pre-
vent the bike fork from turning with the stem shaft.
›
Holding the handlebar by the handles, turn it from
right to left 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 fixture inside the stem.
›
Set the handlebar stem to the required height.
›
Align the handlebar so that it is exactly at right
angles to the front wheel.
›
To secure the stem shaft again, turn the stem ex-
pander bolt clockwise using an Allen key until it is
tight (see
).
