INFORMATION ON THE HANDLING AND USE OF BIKE FRAMES MADE FROM CARBON (CFRP)
TO AVOID DAMAGE TO PERSONS AND PROPERTY WE ASK YOU
TO FOLLOW THESE INSTRUCTIONS.
The use of carbon (carbon fi ber reinforced plastic / CFRP) makes it possible for us to produce
high-performance 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 property damage in the event of improper use, assembly errors or
poor maintenance and care. That is why being knowledgeable about this material is
important for enjoying a carbon frame in the long term.
When these products are overstressed, no lasting deformations are visible even though the
inner structure could be damaged. In addition, rock impacts 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..
CONTACT YT INDUSTRIES IMMEDIATELY AFTER YOU HAVE A FALL!
Pay attention if your carbon frame makes unusual snapping noises. This could be a sign of
an impending material defect. If this occurs, stop using the bike immediately.
IF THE FOLLOWING OCCURS, IT IS ABSOLUTELY ESSENTIAL TO HAVE THE
FRAME INSPECTED BY YT INDUSTRIES:
After a fall
Other major mechanical stresses
Unusual noises from the frame (e.g. snapping sounds)
INFORMATION ON FRAME CONSTRUCTION
The manufacture of these high-end products is done by hand.
This can lead to differences in the fi nish which are not cause for complaint.
HOW TO CORRECTLY HANDLE YOUR CARBON FRAME:
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 cable clamp / seat post:
The prescribed tightening torque of the seat cable clamp bolt is 5 Nm.
The seat post must not be rubbed or otherwise 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.
Carbon Handlebar:
Installing carbon handlebars requires great care and precision. Do not exceed the
specifi ed 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 specifi cations 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 fi ttings 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.
CARE INFORMATION:
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 cleaners with normal additives 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
Deformation (bulges, etc.)
Discoloration
SURFACE PROTECTION:
YT Industries carbon frames are equipped with protective foils or protectors made of
polyamide or polyurethane at points which are exposed to particular 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.
IF NO WHEEL INSTALLED KEEP REAR WHEEL AXLE LOOSE!
USE TRANSPORT LOCK!!
CHECK PROTECTION FOILS REGULARLY!
