fitting. No other derailleur mountings
may be used.
Maximum torque for fitting the derail-
leur clamp coll ar on the seat tube is
4Nm 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-relat ed deformation and
damage and must be avoided.
2.4.— Headset
Fully or semi-integrated headsets are
used in carbon frames fo r op timum rigid-
ity values and optimum distribution of
forces and hi gh levels of security.
• Un authoris ed milling work is not
permissible and will re sult in the
guarantee being in validated.
Delivery is with headset instal led. Any
change of headset must be agreed with
the manufacturing company. Press-
fitting the head set shell bearin gs mu st
be perfor me d using a specially designed
tool. Press fitting must be performed
with caution and it mu st be ensured
that the shell bearin gs do not twist. The
shell bearin gs must not be greased at
points where they are in contact with
the frame. The side facing the bearing
should be gr eased to ensure long life
of the headset
2.5.— Bottom bearing / crank
inside bearing system
The bottom bearing must be fitted usin g
a tool specially designed fo r the task.
Only bottom bearin g and crank inside
bearing systems designed for “BSA” or
„Pressfit“ types may be used. The inner
bearing thread should be rethreaded
with a suitable threadin g die an d be
thoroughly greased. When fitting the
inner bear in g it must be ensured that on
the right hand side seen from the direc-
tion of travel there is a left-han d thread
in the bottom bracket (the inner be aring
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 cloc kwise). The
torque stipulated by the relevant manu-
facturer should be ob served and the
maximum inner bear in g torque is 50Nm
(min. 45Nm) (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 as sembly has
been designed and built for a hub width
of 13 0mm (racing bike) and 135 mm (MTB
Hardtail ) and 135/ 14 2mm (MTB-Fully).
On the rear assembly only hubs of
130mm (racing bike) an d 135mm (MTB-
hardtail ) and a quick-release mechanism
must be used. For the Fully models
135mm a quick-release mechanism an d
a 14 2mm Syntac e X12 axle.
The use of hu bs with other dimen sions
and/or without quic k-release mechanism
may result in stress and disten sion
conditions, which can lead to serious
damage and therefore pres ent a risk to
safety. The rear assembly is designed
