General information
For these reasons, an element or frame made of
CFRP can fail without perceptible warning.

• Be careful when using U-locks – under certain
circumstances, they can cause damage to your
frame.

used.
2 4 y t
• 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.
C A R E I N F O R M A T I O N
Your carbon frame needs regular care. Common
paint care products with or without silicon additives
and cold to lukewarm water are suitable for cleaning.
You can add common dish detergents to the cold to
lukewarm water.
All solvents must be avoided:
• alcohols (e.g. ethanol or isopropanol)
• hot water with alkaline additives
• do not clean with steam jets or high-pressure
cleaners
Check whether your frame has external damage at
regular intervals (e. g . during maintenance):
• cracks
• paint damages
• discoloration
• deformation (bulges, etc.)
S U R FA C E P R O T E C T I O N
YT Industries carbon frames are equipped with
protective foils or protectors made of polyamide or
polyurethane at points which are exposed to particu-
lar stress.
Other points could form due to different application
areas and conditions (e.g. wearing knee protectors).
These areas must be protected against damage or
abrasions with additional protective foils.
• Please check at regular intervals whether the
protective foils are still functional.
• We recommend replacing the protective foil around
tension points once a year.
