racing bike gear shifters are operated dif-
ferently. A RED shifter serves as an example here:
The shifter behind the right hand brake lever
switches the chain on the rear sprockets. Operat-
ing the shifter over its short travel switches to a
smaller sprocket and with the longer travel to a
larger one.
Your bicycle is supplied with the cor
-
responding operating manual for
your specific gear system. You can
get more information about the gears on your
bicycle in the operating manual provided by
your manufacturer or on the manufacturer‘s
website.

The shifter behind the left hand brake lever
switches the chain onto the small chain wheel at
the front over its short travel and onto the large
chain wheel with the longer travel.
Gears are vital to your safety on
the bike! Please read the operating
instructions supplied to you by your
manufacturer and familiarise yourself with
how to operate the bicycle and switch gears
before your first ride. Allow your specialist re
-
tailer to undertake any work on your bicycle‘s
gears! Work that is improperly carried out en
-
dangers your safety on the bicycle!
Do not pedal backwards while chang
-
ing gears as this could damage the
gear system. Changes to the setup
of your gears should only be made in small
steps and with the greatest of care. Incorrect
setup work can lead to the chain coming off
the sprockets and causing a fall. If you are
at all unsure, contact a specialist retailer who
can set this up for you.
Despite a perfectly set up chain gear
system, a bike chain crossing at an
angle can lead to noises during rid-
ing. These noises are normal and do not
cause any damage to the gear components.
This noise will not occur when the bicycle
chain runs at a flatter angle in another gear.
