GEARS: HOW TO OPERATE
Derailleur Gears
Derailleur gears are the most common type
of gear systems used on bicycles. They are the
changing mechanism used to move the drive chain
up and down a series of cogs or sprockets
(the cluster or cassette stack) at the rear of the
bicycle and across the chainwheel at the front
of the bike (if fitted). Multispeed bicycles today can
range form 5-6 gears to as many as 30.
Rear derailleurs are fitted to all multispeed bicycles
while front derailleurs are only present on those
bicycles with the higher number of gears.
Gears enable the cyclist to select the most
appropriate pedalling resistance best suited
for the riding conditions. The more gears fitted
to the bicycle the greater choice available
to the rider.
