Most clamps are potential sources of damage to large-diam-
(a)
eter frame tubes that are not designed to be fixed in such
clamps!
This can result in irreparable damage to the frame. High-end, very
thin-walled aluminium frames are particularly susceptible to such kind of
damage.
Suitable, special-purpose models are, however, available at your BMW
partner.

Rear carriers are becoming more and more popular. Their big advan-
tage over roof carriers is that you do not have to lift up the bicycles so
high to attach them. Make sure the fastenings do not create any damage
to the fork or frame. Risk of breakage!
Please make sure the lights and the number plate of your car
are not hidden from view. For some carriers, a second exterior
rear view mirror is required by the road traffic regulations.
Do not buy a carrier on which the bicycle has to be mounted
upside down, i.e. with the handlebars and saddle fixed face
down to the carrier. This way of fastening the bicycle exposes
handlebars, stem, saddle and seat post to extreme stress dur-
ing transport. Do not opt for a carrier system with crank arm fit.
Risk of breakage!

Whatever system you opt for, make sure it complies with the relevant
safety standards of your country.
Read the instructions of your bicycle carrier and observe the maximum
load capacity and recommended or prescribed driving speed.
Check whether your bicycle is properly fastened before and at
regular intervals during the ride. A bicycle that detaches from
the roof carrier may endanger other road users.
Bear in mind that your car has a greater overall height with
the bicycle on it. Measure the overall height and place a sign
stating the height somewhere in the cockpit or on the steering
wheel so that it can be easily seen.
Never transport bicycles with hydraulic brakes upside down.
This could let air enter the brake system and result in brake
failure.
If your bicycle has disc brakes, be sure to mount the safety
locks before transporting the bicycle with the wheels dis-
mounted.
