fitting. No other derailleur mountings
may be used.
Maximum torque for fitting the derail-
leur clamp collar on the seat tube is
4 Nm and must be fitted in intermediate
steps. When fitting a torque wrench it is
important to avoid deformation of the
seat tube in the vicinity of the clamp.
•
Damage to the seat tube in the
vicinity of the derailleur clamp by
excessive tightening or incorrect
size of clamp collar may lead to
safety-related deformation and
damage and must be avoided.
2. 4. — Headset
Fully or semi-integrated headsets are
used in carbon frames for optimum rigid-
ity values and optimum distribution of
forces and high levels of security.
•
Unauthorised milling work is not
permissible and will result in the
guarantee being invalidated.
Delivery is with headset installed. Any
change of headset must be agreed with
the manufacturing 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
2. 5. — Bottom bearing / crank
inside bearing system
The bottom bearing must be fitted using
a tool specially designed for the task.
Only bottom bearing and crank inside
bearing systems designed for “BSA” or
„Pressfit“ types may be used. The inner
bearing thread should be rethreaded
with a suitable threading die and be
thoroughly greased. When fitting the
inner bearing it must be ensured that on
the right hand side seen from the direc-
tion of travel there is a left-hand thread
in the bottom bracket (the inner bearing
element is screwed in anticlockwise). On
the left side seen from the direction
of travel the bottom bracket bush has
a right-hand thread (the inner bearing
element is screwed in clockwise). The
torque stipulated by the relevant manu-
facturer should be observed and the
maximum inner bearing torque is 50 Nm
(min. 45 Nm) (see Pages 11/12). The Press-
fit inner bearing must only be press-
fitted using the tool specially designed
for the purpose.
2. 6. — Rear assembly.
Your carbon frame rear assembly has
been designed and built for a hub width
of 130 mm (racing bike) and 135 mm (MTB
Hardtail) and 135/142 mm (MTB-Fully).
On the rear assembly only hubs of
130 mm (racing bike) and 135 mm (MTB-
hardtail) and a quick-release mechanism
must be used. For the Fully models
135 mm a quick-release mechanism and
a 142 mm Syntace X12 axle.
The use of hubs with other dimensions
and/or without quick-release mechanism
may result in stress and distension
conditions, which can lead to serious
damage and therefore present a risk to
safety. The rear assembly is designed
