9.3.5 Adjusting the handlebar height with an
adjustable handlebar stem
With some types of handlebar stems, you can vary the
handlebar tilt. The stem angle can be adjusted via the
clamping screws which are on the side of the articulation
or the top/bottom of the stem. Models equipped with ad-
ditional stop notches or adjusting screws are available.
Hexagon socket screw
(integrated stop notch)
Adjusting screw
Adjust the handlebar tilt as follows:
Undo the clamping screw by turning it anticlock-
wise through two or three revolutions using an
Allen key.
If you own a model that is also equipped with
detents, continue turning the clamping screw anti-
clockwise to disengage the detents.
If you own a model with integrated stop notch,
loosen the screw of the stop notch. In many stem
types this is located on the underside of the stem.
Tilt the handlebar stem to the required angle.
To fasten the handlebar stem, tighten the clamping
screw clockwise using an Allen key . If tightening
torques are specied on the stem, use exactly these
torques, and if not, refer to the table of tightening
torques in
Chapter 30 "Technical data".
In models with an integrated stop notch, tighten
the screw of the stop notch carelly clockwise.
In doing so, the stop notch must engage with the
teeth.
10 Frame
The form of the ame depends on the bike type and nc-
tion. Frames are manufactured om dierent materials
– steel or aluminium alloys or carbon (carbon bre), for
example.
The ame number of the bike is stamped on the seat
tube, the dropout or the bottom bracket housing.
It may also be found on the motor suspension in Pe-
delecs. The bike can be identied by the ame num-
ber if it is stolen. To identi the bike properly, it is
important to note down the whole number in the right
order.
Never ride your bike if the ame is warped or
cracked. On no account should you attempt to repair
damaged parts. This can lead to accidents. Replace
defective parts before you ride the bike again.
Aer an accident or crash, have your bike checked by
a professional bike workshop before riding it again. If
defects on the ame or components go unnoticed this
can lead to accidents.
If your bike does not roll forwards easily in a straight
line, this could mean that the ame is warped. In this
case, have the steering stability checked by a profes-
sional bike workshop.
