Your bike has
A derailleur gear, easily recognisable by a
sprocket set on the rear hub and a crank
wheel set with several chain rings or
a hub gear, recognisable by a “fat” rear wheel
hub.
These gears provide you with the optimum gear for
any speed and amongst other things make climbing
inclines easier.
You can find out the number of gears as follows:
Derailleur gears: Multiply the number of crank
wheel sprockets at the front with the number
of sprockets on the rear sprocket set. For
example, 3 crank wheel sprockets x 9 rear
sprockets = 27 gears.
Hub gears: The number of gears is indicated
by the highest number of gears shown on the
gear selector.

5 Before using for the first
time
RISK OF PERSONAL INJURY AND
MATERIAL DAMAGE!
An unroadworthy bike can lead to dangerous riding situations, falling, accidents
and material damage This same danger
exists if you are not yet familiar with
your new bike and its controls.
Familiarise yourself with this bicycle
before you first ride it. In particular check with brake lever operates
the front brake and which the rear –
see Section 7.7.
Modern brakes have a very power-
ful braking effect. Excessively strong
operation of the brake levers can
cause the respective wheel to lock
and can therefore lead to a fall.
Familiarise yourself slowly with the
braking effect on your bike in a safe
area of land.
With new rim brakes and after re-
placing brake blocks the full braking
effect only develops after a certain
run-in period. Please note therefore your initially greater braking
distances.
Disk brakes need to be initially run
in. Full braking efficiency only develops after the running-in process.
Please note the enclosed brake
manufacturer‘s running-in instructions.
A rule of thumb is: Ride 1 km with
permanent razing brakes, following
2 hard braking procedures from a
speed of approximately 30 KPH ( ...
19 miles per hour)
If your bike is fitted with optional
click-in pedals which firmly connect
the shoe with the pedal:
Practice using them by mounting and
dismounting.
Click-in pedals are not safety pedals.
If after purchasing you remove
the saddle support and front and/
or rear wheel for transportation
please follow the appropriate instructions in Chapter 10.1 and 10.2.
1. Have your dealer confirm proper final
assembly and the roadworthiness of your bike.
2. Have your dealer adjust the correct saddle
position.
You can make fine adjustments and minor changes yourself as described in
Chapter 6.2.2 “Adjusting the saddle position”.
3. Only use this bike when your dealer has
familiarised you with your bike’s technical
features in a briefing.
4. Seal you bike with aerosol wax polish, see
Chapter 11.
5. Before using read Chapter 6.
BEFORE EVERY TRIP ROAD BIKE | EN | 13
6 Before every trip
RISK OF PERSONAL INJURY AND
MATERIAL DAMAGE!
An unroadworthy bike can lead to dangerous riding situations, falling, accidents
and material damage
Also consider the possibility that your
bike may have fallen over when unattended or that someone might have
tampered with it.
Check that your bike is roadworthy
before every trip.
Memorise your bike‘s correct condi-
tion when new so that you will later be able to recognise deviations
from the correct condition (photos
you take yourself can be a valuable aid).
Contact your dealer immediately if
you discover that your bike‘s condition is different from normal.
Only ride the bike again after it has
been properly readjusted by the
dealer.
1. Visually inspect the whole bike:
Check all fixing screws for correct
tightness (see Chapter 1.2.4)
Check the entire bike for dents, ruptures,
deep scratches and other forms of
mechanical damage.
Contact your dealer if visual inspections shows
defects of any description.
6.1 Check the wheels
Front and rear wheels are both called
wheels.
A wheel consists of
the hub,
On the rear wheel hub only Sprocket or
sprocket cassette,
Brake disk, if fitted,
Spokes
Rim and the
Tyre equipment, which in turn consists of
— Tyre casings,
— Tube and
— Rim tape insert.
Many bikes are fitted with tubeless tyre road
wheels. On these tyres with no tube are fitted on
special rims. A tube can also be fitted however.
On StVZO-equipped bikes rim reflectors may be
fitted.
6.1.1 Check fitting
1. Shake both wheels at right angles to the
direction of travel.
The wheels must not move in the forks.
There must be no audible creaking or
rattling sounds.
Contact your dealer if this check shows defects of
any description.
6.1.2 Check the rims
RISK OF PERSONAL INJURY AND
MATERIAL DAMAGE!
Worn rims and/or substantial warping or
run-outs may lead to hazardous riding
situations, falling, accidents and material damage.
Worn rims must be replaced and warping
or run-outs repaired!
RISK OF PERSONAL INJURY AND
MATERIAL DAMAGE!
With rim brakes: Dirty rims may reduce
braking efficiency.
Dirty rims must be cleaned immediately.
14 | ROAD BIKE | EN
Racingbike011, wear indicator ()
Racing bike012, wear indicator ()
Racing bike013, wear indicator ()
1. Check rims for wear:
Rims with wear indicators:
Visual check
Rims without wear indicators:
Visual check
Fingernail check: Run your fingernail
across the rim shoulder. No scoring
should be felt.
If the wear indicator is no longer visible or
if the rim has discernible scoring the rim
must be replaced.
2. Check rims for run-out:
Lift the bike up and spin first the front and
then the rear wheel.
Note the distance between the rim and
the brake shoes and on disk brakes the
distance between the rim and the frame
strut or fork leg.
Maximum permissible deviation per
revolution is 1 mm.
3. Check your rims for dirt, especially oil and
grease.
Dirty rims must be cleaned immediately (see
Chapter 11)
6.1.3 Check tyres
1. Check the valve position:
Does not apply to tubeless tyres.
RISK OF PERSONAL INJURY AND
MATERIAL DAMAGE!
In the event of angled valve the base of
the valve can rip off when riding which
causes sudden loss of tyre pressure.
This can lead to hazardous riding situations, falling, accidents and material
damage.
Have the tyre seating corrected by a
specialist workshop.
You can undertake this job yourself if
you are familiar with fitting and removing
the road wheels (see Chapter 10.1) and
replacing the tyre and tube.
Remove the valve nut.
Check the valve position:
The valves must point directly towards the
centre axis of the road wheel.
BEFORE EVERY TRIP ROAD BIKE | EN | 15
Racing bike 015, valve pointing to wheel axis
Racing bike014, valve not pointing directly to wheel
axis
2. Check the tyre pressure:
Determine your tyre type
Mountain bikes can be fitted with racing bike type tyres and racing bikes with
trekking tyres.
Rule of thumb:
Mountain bike tyres: Tyre width greater
than 40 mm
Trekking / Cross-country and Fitness bike
tires: Tyre width from 28 mm – 40 mm
Racing bike style tyres: Tyre width less
than 28 mm
Consult your dealer to determine your
tyre type.
Pressures:
Mountain bike tyres: 2.0 – 3.5 bar
Trekking bike tyres: 3.5 – 5.0 bar
Racing bike tyres 6.0 – 10.0 bar
RISK OF PERSONAL INJURY AND
MATERIAL DAMAGE!
Too low a tyre pressure leads to increased likelihood of punctures but
mostly dangerous handling. The tyre can
come off the rim on bends and cause
wandering of the tyre on the rim. This
can lead to hazardous riding situations,
falling, accidents and material damage.
Inflate your tyres to the correct pressure.
Many tyre pressures are given in “psi”.
Convert the pressure using the following table.
psi 30 40 50 60 70 80 90 100 110 120 130 140
bar 2,1 2,8 3,5 4,1 4,8 5,5 6,2 6,9 7,6 8,3 9,0 9,7
The actual permissible tyre pressure can be found
in the tyre and rim manufacturer’s instructions. The
permissible tyre pressure is mostly embossed on
the tyre wall. Please consult your dealer.
The higher your body weight the higher
the tyre pressure needs to be.
Check the tyre pressure with a tyre pressure
gauge. Simple gauges are often included with bicycle tubes and higher quality gauges are available
from your dealer. How to use them is either in the
instructions for used or you can have your dealer
demonstrate this.
If pressure is too low: Increase the pressure by inflating with a suitable pump.
If pressure is too high: Release sufficient air via
the valve and check the pressure again afterwards
with a gauge.
Using a bicycle pump with a pressure gauge you can check the pressure
whilst inflating the tyre. Let some air out
of the tyre first and then increase the
pressure to the desired level.
