Operation Manual
7. If your bicycle has suspension, check the frame: Press down on your
bicycle and see whether the spring elements retract and extend as usual
.
For more information see chapters and
. Further notes regarding full-suspension bicycles and forks may
be enclosed with this manual.
8. If your bicycle has a kickstand, make sure it is fully raised before you set
off.
Do not use your bicycle, if it fails on one of these points! Riding
a defective bicycle can result in serious accidents! If you are in
doubt or if you have any questions, please contact your bicycle
dealer!
During use your bicycle is undergoing stress resulting from
the surface of the road and through the rider’s action. Due to
these dynamic loads, the different parts of your bicycle react
with wear and fatigue. Please check your bicycle regularly for
wear marks, scratches , bent parts, colour changes and
any indication of cracking. Parts which have reached the end
of their lifespan may break without previous warning. Let your
dealer maintain and service your bicycle regularly and in cases
of doubt it is always best to replace parts.
Do not forget to take a high quality D- or chain lock with you
on your ride. The only way to effectively protect your bicycle
against theft is to lock it to an immovable object.

Your bicycle has undergone numerous tests during production and a final
check has been carried out by your bicycle dealer. Nevertheless, be sure to
check the following points to exclude any malfunctioning that may be due to
the transport of your bicycle or to work a third person may have performed
on your bicycle before delivery:
1. Are the quick-release levers of the front and rear wheel properly closed
and the bolts of the seat post and other components correctly tightened
? For more information see chapter
Improperly closed quick-releases can cause bicycle compo-
nents to come loose. Risk of an accident!
2. Are the tyres in good condition and do they have sufficient pressure?
Make a “thumb test“ . For more information see chapter
.
3. Spin the wheels to check whether the rims are true. Watch the gap be-
tween rim and brake pad or, in the case of disc brakes, between frame
and rim or tyre. Untrue rims can be an indication of tyres with ruptured
sides or broken axles or spokes. For more information see chapter
.
4. Test the brakes while stationary by firmly pulling the brake levers towards
the handlebars .
The brake pads of rim brakes must hit the rim with their entire surface
without touching the tyre. You should not be able to pull the lever all
the way to the handlebars! The same applies to the brake levers of disc
brakes. You should not be able to pull them all the way to the handle-
bars! Make sure there is no brake fluid leakage. Also check the thickness
of the brake pads. For more information see chapter .
5. Let your bicycle bounce on the ground from a small height. If there is
any rattling, check where it comes from. Check the bearings and bolts, if
necessary.
6. If you want to ride on public roads, make sure your bicycle is equipped
according to the regulations of your country . Riding without lights and
reflectors in dark or dim conditions is very dangerous, because other
road users will see you too late or not at all. A set of lights that corre-
sponds to the regulations is a must on public roads. Turn on the lights as
soon as dusk sets in. For more information see chapter
.
