GEARS - HOW TO OPERATE

Derailleur Gears

Most multi-speed bicycles today are equipped with what
are known as derailleur gears. They operate using a system
of levers and mechanisms to move the drive chain between
different sized driving gears or cogs. The purpose of gears
is to let you maintain a constant, steady pedaling pace
under varying conditions. This means your riding will be
less tiring without unnecessary straining up hills or fast
pedaling down hill. Bicycles come with a variety of gear
configurations from 5 to 27 speeds. A 5-6 speed bicycle
will have a single front chain-wheel, a rear derailleur, and
5 or 6 cogs on the rear hub. Bicycles with more gears will
also have a front derailleur, a front chainwheel with 2-3
cogs, and up to 7 cogs on the rear hub.

Operating Principles

No matter how many gears, the operating principles are
the same. The front derailleur is operated by the left shift
lever and the rear derailleur by the right. To operate, you
must be pedaling forward. You can not shift derailleur
gears when you are stopped or when pedaling backwards.
Before shifting, ease up on your pedaling pressure. For
a smooth gear change when approaching a hill, shift to a
lower gear BEFORE your pedaling speed slow down too
much. When coming to a stop, shift to a lower gear first so
it will be easier when you start riding again. If, after
selecting a new gear position, you hear a slight rubbing
noise from the front or rear gears, gently adjust the
appropriate shifter using the barrel adjusters until the noise
goes away. For optimal performance and extended chain
life, it is recommended that you avoid using the extreme
combinations of gear positions (diagram page 22) for
extended periods.
