If you have fallen
If you should find any cuts, rips or holes,
please refrain from riding! First have your bicycle
checked over by a specialist.
Before each ride
Before every ride, please check that:
• The lights and bell are working and safely se-
cured
• The brakes are working safely and are properly
secured
• The cables and fittings are not leaking if you
have a model with hydraulic brakes
• The tyres are free of foreign objects and dam-
age, and the rims are not damaged and run
true,
particularly after riding off road
• The tyres have a sufficient tread depth
• The suspension components are working prop-
erly and are safely secured
• The screws, nuts, through axles and quick re-
leases are firmely placed (see page 10 and
37).
• There are no deformations or cracks on the
frame and fork
• The handlebars, stem, seat post and seat are
both correctly and securely fastened as well as
set up in the right position
• The seat post and seat are secure. Try turning
the seat or tipping it upwards or downwards. It
should not move.
• If you are using clipless/magnet pedals, please
check that they are working properly. The ped-
als should release easily and smoothly
• From BMX bicycles: Safe operation of the rotor,
safe attachment of the handlebars to the stem
and of the axle pegs.
If you are unsure of whether your bi-
cycle is in a sound technical condi-
tion, take it to a specialist retailer to
be checked instead of riding it!
It is particularly important if you use your
bicycle a lot, either through sports riding or
daily use, that you regularly have all the im-
portant parts checked by a specialist retailer.
Frame and fork, suspension components
and other parts relevant to your safety such
as brakes and wheels are subjects to heavy
wear, which can impact the operating safety
of these parts.
If you use parts for longer than their intend-
ed lifetime, these can fail without warning,
which can in turn lead to falls and serious
injury!
Please make these checks before
continuing after a fall or if your bicy-
cle falls over!
Aluminium parts cannot be safely
bent back into shape, while carbon compo-
nents can sustain damage which is not recog-
nisable to the eye.
Allow the bike to be checked by a special-
ist retailer.
Check the entire
bicycle for dam-
age. It could have
dents and cracks
in the frame and
the fork as well as
bent components.
When parts of the
handlebars or the
seat were shifted
or twisted, the respective parts must be checked
for functionality and safe attachment.
• Look carefully at the frame and the fork. Defor-
mation can usually be seen quite clearly when
you look at the surface from different angles.
• Look whether the seat, seat post, stem or han-
dlebars are still in their correct position. Do NOT
twist or bend the component from its changed
position without opening the respective screw
connection. It is essential that you adhere to the
fastening torque prescribed when fastening the
components. The appropriate information can
be found on page 37 and in the Chapter “Quick
release”, page 10.
• Check whether both wheels are correctly and
securely attached to the frame and the fork.
• Lift the front wheel and turn it and then lift the
rear wheel and turn it. The rim must run straight
and centrally through the brakes. The tyre may
not touch the brakes. The distance between the
frame or the fork and the tyre indicates whether
a wheel runs in a central position in bicycles
with disk brakes.
• Test whether both brakes have full functionality.
