To make adjustments to your front derailleur, use the
adjusting screw on your shifter to set the free chain
line of the front derailleur.
The front derailleur also has two screws for setting
the limit stop. Shift to the small chain ring and adjust
your front derailleur using the inside end stop screw
to prevent the chain from falling off the smallest chain
ring. Switch to the largest chain ring and use the out-
side screw to set the limit stop and adjust your front
derailleur. Do not let the chain come off the chain ring
on the outside.
Location of the limit stop screws to the inner and
outer stop position may differ with the shifter. For this
reason, please be absolutely sure to observe additional
instructions of the shifter manufacturer.
Improperly adjusted shifter.
Incorrect shifting on
public roads may distract one’s attention from traffic
and potential risks, which may result in an accident or
crash. Check the settings of the shifter during a test
drive away from road traffic.
Bent shifter components.
After a crash, the shifter,
derailleur hanger or front derailleur may be bent.
Proper and safe use can no longer be assured. Have
the defective shifter components replaced by a bike
specialist.
Incorrectly set front derailleur.
The front derailleur
setting is very sensitive. Setting it improperly may
cause the chain to fall off. The bike will no longer be
propelled forward as a result and there is a risk of
crashing. Exercise utmost care when setting the front
derailleur or have this done by a bike specialist.

Gear hubs
The advantage of gear hubs lies in their enclosed
construction. In most cases, you can switch through
all gears with one shift operation. A thumb shift is
used to change gears. By pushing the large shifter
with your thumb, you will change to a higher gear.
By pushing the small shifter with your index finger,
you will change to a lower gear.
Adjusting gear hubs
Gear hubs must rarely be set or adjusted. Normally,
settings are only made using two marks on the hub
and their position by means of an adjusting screw on
the shifter.
Inside bearing and cranks
The inside bearing is normally an enclosed construction
containing the crankshaft and crank assembly. This
construction prevents dirt, water and mud from entering
and requires no maintenance. However, you should
check regularly to make sure the inside bearings in the
bottom bracket shell of the frame is firm.
Check to make sure both crank arms are securely
seated by shaking them; there should be no play.
The location of the brake levers may vary depending
on the model and manufacturer. Read the enclosed
owner’s manual from the derailleur manufacturer.
Gear hubs may require shifting without a load or the
cyclist to stop pedalling when shifting. Make sure that
shifting is noiseless. Read the enclosed owner’s manual
from the derailleur manufacturer.
Failure to remain alert on public roads.
Practicing
braking on public roads may distract one’s attention
from traffic developments, pose potential risks and
cause an accident or crash. Only practice shifting when
on a surface away from traffic.
Observe the owner’s manual of the gear hub
manufacturer when adjusting the gear hub.
