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30speeds.A5or6speedbicyclewill
typicallyhaveasinglefrontchainwheel,arearderailleur,and5or6
cogs on the rear hub. Bicycles with more gears will additionally have
afrontderailleur,afrontchainwheelwith2-3cogs,andupto10cogs
on the rear hub.

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slows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, some adjustments may be
necessary.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(Refertodiagramonpage
29)forextendedperiods.Itisrecommendedthatatrainedbicycle
technician perform all adjustments to the shifters and derailleurs.
