Derailleur Gears.
Most multi-speed bicycles today are equipped with what are known as derailleur
gears. The operate using a system of levers and mechanisms to move the drive
chain between different sizes driving gears or cogs. The purpose of gears is to
let you maintain a consistent, steady pedaling pace under varying conditions.
this means your riding will be less tiring without unnecessarily straining up hills
to fast pedaling down hill. Bicycles come with a variety of gear configurations
form 5 through to 24 speed. A 5-6 speed bicycle will have a single front chain
wheel, a rear derailleur only and 5 or 6 cogs on the rear hub. Bicycles with more
gears will also have a front derailleur, a front chain wheel with 2-3 cogs and up
to 8 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 cannot shift derailleur gear
when you are stopped or when pedaling backwards. Before shifting ease up on
you 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 do 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.
