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 traffic 

licensing regulations in your country (the Road 

Traffic Licensing Regulations (StVZO) in Germany 

for example). Non-approved roof and rear-mount-

ed bike carriers are not safe for use in traffic 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 off 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 from 

the bike before setting off.

›

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 

frame. 

›

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 frame and fork of the bike could 

be damaged.

You can also find important information on using and 

fitting add-on components and accessories in the 

Internet on the pages of the relevant manufacturer.

26   Carbon  components

Carbon is a specific 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 fi-

bres have been destroyed or have detached although 

this is not evident externally. 

You should therefore inspect the carbon frame and all 

other carbon components very carefully if you come off 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 off. 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 frame and a bottom bracket 

housing for a BB30 bottom bracket please note the 

following:

In this case you can fit 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 frame 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-
