25 Bike carriers for mounting on
roof and rear of car
› Only use roof and rear-mounted bike carriers
that meet the requirements of the road trac
licensing regulations in your country (the Road
Trac Licensing Regulations (StVZO) in Germany
for example). Non-approved roof and rear-mount-
ed bike carriers are not safe for use in trac and
can cause accidents.
› Adjust your driving to take the load on your car
roof into account. Bear in mind that your car's
overall height has changed.
The bike could come o the carrier and cause a seri-
ous accident. When transporting the bike, check regu-
larly that it is still securely fastened.
Loose parts such as tools, luggage and tool kits, child
seats, tyre pump, etc. could detach in transit and en-
danger other road users. Remove all loose parts om
the bike before setting o.
› Avoid transporting the bike upside down. Only
attach the bike by the handlebar, handlebar
stem, bike saddle or seatpost if so intended
by the manufacturer of the carrier. Do not use
mountings that could damage the bike fork or
ame.
› Do not attach your bike to the roof or rear-mount-
ed carrier by its pedal cranks. Always attach
bikes by their wheels when transporting them,
unless the carrier is designed for something else,
as otherwise the ame and fork of the bike could
be damaged.
You can also nd important information on using and
tting add-on components and accessories in the
Internet on the pages of the relevant manufacturer.

26 Carbon components
Carbon is a specic material that requires special han-
dling and care when setting up and carrying out mainte-
nance on the bike as well as when riding and also during
transportation and storage.
26.1 Properties
Carbon parts must not be deformed, dented or bent
following an accident or crash. It is possible that -
bres have been destroyed or have detached although
this is not evident externally.
You should therefore inspect the carbon ame and all
other carbon components very carelly if you come o the
bike or if it falls over. If you are not absolutely sure that
the bike is still in a sound condition, have the carbon com-
ponents in question checked by an expert.
26.2 Torques
Some carbon components require lower tightening
torques than metal components. If the tightening
torques are too high, this can lead to hidden damage
that may not be visible externally. Frames or other
components can break or change to the extent that
they could fall o. You should therefore always ob-
serve the information enclosed by the manufacturer
with the component(s) or ask a specialist dealer for
advice. Use a torque wrench to ensure the right tight-
ness is maintained.
If your bike has a carbon ame and a bottom bracket
housing for a BB30 bottom bracket please note the
following:
In this case you can t an adapter so that a bottom
bracket with conventional BSA thread can be used.
However, bear in mind
• You can only install the adapter if the ame is
completely undamaged. Repairing a defective
BB30 housing serves no purpose. If it is not
installed correctly, the bottom bracket housing
may be damaged which would render the war-
