3.5 Headset
Fully or semi-integrated headsets are used
in carbon frames for optimum rigidity values
and optimum distribution of forces and high
levels of security.
Risk of Personal Injury and Material
Damage!
Unauthorised milling work is not per-
missible and will result in the guarantee
being invalidated.
•
Delivery is with headset installed. Any change
of headset must be agreed with the manufac-
turing company. Press-fitting the headset shell
bearings must be performed using a specially
designed tool. Press fitting must be performed
with caution and it must be ensured that the
shell bearings do not twist. The shell bearings
must not be greased at points where they are
in contact with the frame. The side facing the
bearing should be greased to ensure long life
of the headset.
3.4 Front derailleur assembly
Risk of Personal Injury and Material
Damage!
Racing bike frames are designed for either
a braze-on socket derailleur mounting or
for a classic derailleur clamp - MTB frames
have either a classic derailleur clamp, di-
rect Mount or an E-type derailleur fitting.
No other derailleur mountings may be
used.
Maximum torque for fitting the derailleur
clamp collar on the seat tube see page
10/11. When fitting a torque wrench it is
important to avoid deformation of the se-
at tube in the vicinity of the clamp.
Damage to the seat tube in the vicinity of
the derailleur clamp by excessive tighte-
ning or incorrect size of clamp collar may
lead to safety-related deformation and
damage and must be avoided.
3.3 Seat clamp/seat post
Risk of Personal Injury and Material
Damage!
The prescribed tightening torque of the
saddle clamp bolt is 5-6 Nm.
The seat tube must not be scoured or me-
chanically processed in any other way.
Please consult your authorised specialist
retailer immediately after a fall.
The seatposts and seat tubes must not be
lubricated. Only a carbon assembly paste
may be used.
Frame and forks must be examined parti-
cularly carefully for damage (e.g. cracks,
delamination, discolouration etc.) before
and after each instance of use in racing.
After serious crashes or accidents the
frame and forks must not be ridden. The
surface of the frame and forks must not be
damaged. This includes indentations and
large deep scratches which penetrate bey-
ond the first clear coat of lacquer. In case
of doubt the frame and forks must be sent
in for checking.
3.2 How to use your carbon parts correctly
Risk of Personal Injury and Material
Damage!
1.
Do not, under any circumstances, mount
brackets, screws, clamps or other elements
which exert mechanical pressure on the
carbon tube.
2. Clamping onto bike stands or other wall
brackets:
•
Never clamp your bicycle around the carbon
tube or carbon seatpost in the clamping jaws
of a bike stand.
3.
Please take care when using shackle locks!
These may, under certain circumstances,
cause damage to your frame.
•
When using shackle locks, please ensure that
these only touch the respective carbon tube
at the most, and are not exerting pressure.
Aluminium seatposts may only be moun-
ted using a carbon assembly paste.
The seat clamp may not be closed if the
seat post has been removed.
