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-
