I General User Manual 17
Never tighten the handlebar stem if the maximum
mark or stop mark is above the top of the sha. If you
cannot nd a mark, insert the handlebar stem into
the head tube to a depth of at least 6.5 cm. If you do
not do this, the handlebar stem could come loose or
break.
9.3.2 Adjusting the handlebar height with
A-head systems
With the A-head stems shown here, the handlebar height
must be adjusted by a professional bike workshop.
9.3.3 Aligning handlebars with A-head
systems in relation to the ont wheel
To align the handlebar with the ont wheel, proceed as
follows:
Loosen the hexagon socket screws on the rear of
the handlebar stem by turning them anticlockwise
with an Allen key.
Turn the handlebar so that it is exactly at right
angles to the ont wheel.
Tighten the hexagon socket screw by turning it
clockwise with an Allen key (see
Chapter 30
"Technical data").
9.3.4 Adjusting the handlebar position by
turning the handlebar
Loosen the hexagon socket screws on the ont of the
stem. Turn the handlebar until you nd the position that
is comfortable for you. Make sure that the handlebar is
always exactly in the centre of the stem. Now retighten the
hexagon socket screws by turning them clockwise. If the
tightening torque is stamped on the stem, use this value,
and if not, use the tightening torques in
Chapter 30
"Technical data".
Once you have adjusted the handlebar, you will also need
to adjust the brake levers and gear-shi handles. Loosen
the hexagon socket screws on the handle grips. Sit on
the saddle and put your nger on the lever. Turn the le-
ver until your hand and lower arm are in a straight line.
Retighten the screws in the handle grips by turning them
clockwise. (For tightening torques see
Chapter 30 "Tech-
nical data").
