BEFORE YOU RIDE
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 downhill. Bicycles
come with a variety of gear configurations from 5 to 27 speeds. A 5-6
speed bicycle will have a single front chainwheel, 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 9 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. On approaching
a hill, shift to a lower gear before your pedaling speed slows down too
much for a smooth shift. 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 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 p. 20) for
extended periods.
