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.
