3.1.3 Categorisation of warning notes
The warning notes are intended to draw your attention to poten-
tial hazards. Your complete attention is required when reading the
warning notes; the statements must be understood completely.

11
Safety
Neither the manufacturer nor the specialist dealer will accept lia-
bility for damage which occurs due to improper use, which does
not comply with the intended purpose. Only use the bicycle in the
manner described in this user manual. Any other use is deemed
improper and may cause accidents, serious injuries or damage to
the bicycle itself.
The warranty is rendered void in the event of improper use of the
bicycle.
The bicycle is intended for use by one person, for whom the bicycle
has been adjusted to provide the correct sitting position according
to their body size.
The bicycle is intended for use on paved roads and paths. In light
terrain, e.g. on gravel tracks or field and forest paths, it can be
used with caution. The wheels must have constant contact with
the ground. Any use in rough terrain can cause the bicycle to fail.
The bicycle is not intended to be subjected to above-average strain
during use; e.g. the use of the bicycle in racing or competitive
events is not considered to be in accordance with its intended use.
3.3 Road traffic
WARNING
Improper use or use for purposes other than those origi-
nally intended.
Risk of accident and injury!
• Only use the bicycle in public road traffic if it is equipped
in accordance with the road traffic regulations in the
respective country.
• Be aware of and follow the applicable national and
regional regulations regarding road traffic.
WARNING
No head protection.
Risk of injury!
• Wear a suitable bicycle helmet when riding your bicycle.
WARNING
Poor visibility to other road users.
Risk of accident and injury!
• Wear light-coloured clothing with reflective elements
when riding your bicycle.

12
Safety
WARNING
Not paying sufficient attention to the road traffic.
Risk of accident and injury!
• Do not allow yourself to become distracted by other
activities when riding your bicycle, e.g. by switching the
lights on.
• Do not use mobile devices when riding your bicycle, e.g.
smartphones or MP3 players.
• Do not ride your bicycle if you have consumed alcohol,
narcotics or medication which may impair your ability
to ride.
Note: Dirt roads and forest tracks are also part of the road traffic
network, as are private areas of land if these are accessible to the
public.
• Seek information regarding the relevant applicable road traffic
regulations for your respective country or the region, e.g. from
the Ministry of Transport.
• Ensure that you regularly obtain information regarding
changes to the content of the regulations currently in force.
• Ride in such a way that nobody suffers injury, is endangered,
incapacitated or disturbed.
• Use the cycle routes intended for bicycles according to
regulations.
3.3.1 Bicycle helmet
• For your safety: Wear a bicycle helmet even if you are not
required to do so by law.
• Laws and regulations may change at any time. Check regu-
larly for updates about regulations for your respective country
or region.
• Wear a suitable bicycle helmet which has been tested in
accordance with DIN EN 1078 standards and bears the CE
seal of conformity.
3.3.2 Handlebar extensions
WARNING
Extended braking distance due to greater distance to the
brake levers.
Risk of accident and injury!
• Familiarise yourself with the handlebar extensions and
how to reach over to the brake levers.
• Drive with extra foresight when using handlebar
extensions.

13
Safety
3.3.2.1 Bar ends
The use of bar ends in road traffic is fraught with risks. The path of
the hands to the brake levers is longer and can lead to accidents
in dangerous situations.
Bar ends are additional handles at the end of the standard handle-
bars, which can be used to adopt a better riding position, e.g. on
particularly steep ascents.
3.3.2.2 Triathlon handlebar attachment
Triathlon handlebar attachments are used in order to be able to
adopt an aerodynamic position in triathlons or time trials on a road
bike, for example.
Triathlon handlebar attachments may only be retrofitted to racing
bikes without motor assistance.
Triathlon gear levers are often located at the end of the handlebars.
The brake levers are at the end of the basic handlebar. When the
racing bike is ridden in an aerodynamic position, the brake levers
are out of the rider's direct gripping distance.
• Get familiar with the handling of a triathlon handlebar attach-
ment and how to reach over to the brake levers away from
traffic.
• Exclude other sources of danger, such as unpractised use
of clipless pedals, when practising handling the handlebars.
• Adapt the way you ride to suit the changed handling of the
bicycle.

3.3.3 Additional regulations
For use in road traffic, bicycles must be equipped with two brakes,
which operate independently of one another, and a bell.

Safety
3.4 Modifications
WARNING
Changes to the bicycle or incorrectly selected spare parts
can cause the bicycle to malfunction.
Risk of accident and injury!
• Only use original spare parts.
3.5 Residual risks
Despite the observance of all safety and warning notes, use of the
bicycle is still associated with several unforeseeable residual risks,
some examples are listed below:
– Misconduct of other road users
– Unforeseeable material defects or material fatigue can lead to
breakages or failure of components
• Try to anticipate the actions of others and ride defensively.
• Before each ride, you should check your bicycle for cracks,
changes in colour or other signs of damage.

4.2 Direction of rotation for screws
• Tighten screws, axles and nuts by turning them in a clockwise
direction.
Note: If there are any deviations to this rule, a note will be included
in the appropriate chapter, indicating the change in direction.
Please observe the respective notes.
4.3 Torques
WARNING
Material fatigue caused by incorrect tightening of screwed
connections.
Risk of accident and injury!
• Do not use the bicycle if you notice any loose screwed
connections.
• Screwed connections must be properly tightened with a
torque wrench and the correct torque level.
The correct torques must be observed in order to correctly tighten
screwed connections. This requires the use of a torque wrench
with a corresponding range of adjustment.
• If you do not have any experience with using torque wrenches,
you should ask your specialist dealer to check your screwed
connections.
• Individual bicycle components are labelled with information
about the appropriate torques or with markings showing inser-
tion depths. You must make sure to observe these specifica-
tions and markings.
This table does not list all components. Torque specifications are to
be used as basic values and do not apply to carbon components.

4.4 Sitting position
CAUTION
Muscle tension and joint pain due to an incorrectly
adjusted sitting position.
Risk of injury!
• Ask your specialist dealer to adjust your sitting position
correctly.
CAUTION
Limited accessibility to operating controls on the handle-
bar due to an incorrect sitting position.
Risk of accident and injury!
• Ask your specialist dealer to adjust your sitting position
correctly.
The optimal sitting position depends on the frame size of the bicy-
cle, the physical size of the rider and the settings of the handlebars
and the seat. Specialist knowledge is required to adjust the bicycle
to an optimal sitting position.
The optimal sitting position can also depend on the use of the
bicycle, e.g. if it is predominantly used for sports.
The key features of an optimal sitting position are:
– If a pedal is at the top, the knee angle of the upper leg and the
arm angle is 90°. The lower leg is slightly bent (see Fig. “Key
features of an optimum sitting position”, left).
– If one pedal is in front, the knee should be located above the
axle of the front pedal (see Fig. “Key features of an optimum
sitting position”, right).
– The arms are relaxed and slightly bent outwards (not shown
in the picture below).
– The back is not perpendicular to the seat post.

Fig.: Key features of an optimal sitting position
If the optimal sitting position cannot be achieved by adjusting the
seat and the handlebars, on many bicycle models it is possible to
replace the relevant components.
If selling or passing the bicycle on to another person, this can be
an option to enable continued use of the bicycle.
• If the sitting position cannot be optimally adjusted,
ask your specialist dealer to fit components with different
measurements.
4.5 Wear
WARNING
Malfunction caused by excessive wear and tear, material
fatigue or loose screwed connections.
Risk of accident and injury!
• Check the condition of your bicycle regularly.
• Do not use the bicycle if you notice excessive wear or
loose screwed connections.
• Do not use the bicycle if you notice any cracks,
distortions or changes in colour.
• If you notice any signs of excessive wear and tear,
loose screwed connections, distortion, cracks or col-
our changes, you should get your specialist dealer to
inspect your bicycle immediately.
As with all mechanical components, bicycle components are sub-
ject to wear. High levels of strain and improper use exacerbate
wear. Different materials wear out at different rates.
Only a specialist dealer is able to assess wear on components
made of aluminium, carbon or composite materials.

19
Basic information
Heavy blows, shocks and excessive tension can cause damage
to frames, forks and wheels made of carbon and composite mate-
rials. The inner structure of the materials undergoes detrimental
changes without showing any visible signs.
• Consult your specialist dealer about the wearing parts of your
bicycle.
• Regularly check the condition of all wearing parts.
• Maintain the wearing parts on a regular basis.
4.6 Carbon components
WARNING
Invisible cracks and distortion of carbon components.
Risk of accident and injury!
• Always get carbon components checked over by a spe-
cialist dealer after falls, overloading and heavy impacts.
NOTICE
Increased wear and tear caused by incorrect care and
maintenance of carbon components.
Risk of damage!
• Do not allow carbon components to come into contact
with grease and oil.
4.7 Protection against theft
• Protect your bicycle against theft.
• For models with a frame lock: If you are not able to keep watch
over your bicycle, lock it up using the frame lock.
Note: For effective protection against theft, use a chain lock or
steel cable lock and attach the bicycle to a fixed object, e.g. to a
bicycle stand.
The frame lock does not provide sufficient protection against theft.
4.8 Permissible total weight
Permissible total weight:
– Rim size, children's bike, 20 inches: 45 kg
– Rim size, children's bike, 24 inches: 60 kg
– Rim size, children's bike, 26 inches: 80 kg
– Rim size 26 inches: 130 kg
– Rim size 27.5 inches: 130 kg
– Rim size 28 inches: 130 kg
– Rim size 29 inches: 130 kg
Possible deviations from the permissible gross weights (see Chap-
ter “Bicycle passport” on page 94).
• If you own an e-bike, read the separate user manual on its
drive system to learn the permissible total weight.

20
Basic information
4.8.1 Determining unladen weight
• Determine the unladen weight of your bicycle by weighing it,
with all optional extra equipment attached as appropriate.
Note: For the best results, the weight should be determined using
a hanging scale. If necessary, ask your specialist dealer to deter-
mine the unladen weight of your bicycle.
4.8.2 Calculating the total weight
The actual total weight is calculated as follows:
Bicycle + rider (incl. rucksack) + baggage = total weight
Luggage includes saddle bags and baskets.
4.9 Transport
NOTICE
Incorrect use of bike racks.
Risk of damage!
• Only use approved bicycle racks with which the bicycle
can be transported in an upright position.
• Find out how to use a bicycle rack, e.g. by consulting
your specialist dealer.
• Secure the bicycle properly to prevent it from slipping
and falling off.
Depending on the bicycle model, a transport restraint for the disc
brakes is included in the bicycle’s packaging.
• Ask your specialist dealer to explain how to use the transport
restraint.
• Use the transport restraint when transporting the bicycle.
• Transport the bicycle in an upright position.
