The use of carbon (carbon fiber reinforced plastic /
CFRP) makes it possible for us to produce high-per-
formance products for our customers. Since these
components and frame elements can be sensitive
and delicate under certain conditions, there is a risk
of breaks which could lead to accidents and proper-
ty damage in the event of improper use, assembly
errors or poor maintenance and care. That is why
being knowledgeable about this material is impor-
tant for enjoying a carbon frame in the long term.
When these products are overstressed, no last-
ing deformations are visible even though the inner
structure could be damaged. In addition, rock im-
pacts or messy falls involving impacts on edges
can result in invisible damages and/or delamination
(= carbon layers dissolve) of the carbon material.
For these reasons, an element or frame made of
CFRP can fail without perceptible warning.

Pay attention if your carbon frame makes unusual
cracking noises. This could be a sign of an impen-
ding material defect. If this occurs, STOP using the
bike immediately and turn to YT.

sounds)

The manufacture of these high-end products is
done by hand. This can lead to differences in the
finish which are not cause for complaint.

General information
• Under no circumstances should you install rings,
screw connections, clamps or other elements
which exert mechanical forces on the carbon tube.
• Never clamp the carbon tube or carbon seat post
of your bike on the gripping jaws of a work stand
or bike rack.
• Be careful when using U-locks – under certain
circumstances, they can cause damage to your
frame.
Seat clamp / seat post
• The prescribed tightening torque of the seat
clamp bolt is 5 Nm.
• The seat post must not be rubbed out or other
wise mechanically stressed.
• The seat post and seat tube may not be
lubricated. Only carbon assembly paste can be
used.
• Aluminum seat posts may only be installed when
carbon assembly paste is used.
• The seat clamp must not be closed when the seat
post has been removed. Risk of fracture!
Carbon Handlebar
Installing carbon handlebars requires great care and
precision. Do not exceed the specified torque under
any circumstances and make sure that the stem
does not have any sharp edges or ridges.
• Please note the prescribed tightening torque of
the stem manufacturer.
• Carbon handlebars can only be installed using
carbon assembly paste.
• If you would like to shorten the handlebar, note
the specifications of the manufacturer or contact
us directly.
Rear wheel axle
• To prevent damages to the seat stays, the rear
wheel axle must never be completely closed if the
wheel is not in the frame.
Transport
You must be particularly careful when transporting
bikes with carbon frames:
• Protect the frame in particular from contact with
other parts (use covers, etc.).
• Do not use transport fittings which use clamping
elements. Clamping forces could damage the
frame structure.
• Do not place any objects on the frame.
• Make sure the bike cannot slide around during
transport.
• Never transport without rear wheel or rear section
transport lock assembled.
