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 inuence 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.

height with a conventional handlebar
stem

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.

pander bolt clockwise using an Allen key until it is
