MAINTENANCE
DERAILLEUR SYSTEM
STRETCH
INSPECTION
The operation of the derailleur system should be checked at least every month. Check the operation of
the rear derailleur first, then the front. The rear derailleur should shift the chain cleanly from one cog
to the next without hesitation. Each notched position in the shifter must equate to a new gear position.
After shifting, the rear derailleur should not rub on the chain. The derailleur should never cause the chain
to fall off the inner or outer freewheel cogs.
The front derailleur should also shift the chain cleanly and without hesitation between each chainring. If
your bicycle is equipped with front indexing (a click between gears), then each click or stop in the shifter
should equate exactly to a new gear position. When the chain has been positioned onto a new chainring,
it should not rub on the front derailleur. The chain should not fall off a chainring at any time. Derailleur
control cables are a critical component that must be well maintained for accurate shifting performance.
Check them for any sign of rust, fraying, kinks, broken strands and any damage to the cable housing. If
you find any problems, the cables may need replacing before you ride.
Consult page 42.
HOW THE COMPONENTS WORK
It is very important to understand how the different components of your bike work, to use them effec-
tively, pleasantly and safely. Even if you are an experienced cyclist, do not assume that the operation
of your new bike is the same as other bikes from previous models. Be sure to read and understand this
section of the Handbook. Given the slightest doubt, consult a qualified technician.
When riding a bike with a quick release mechanism set incorrectly, it is possible for the wheel to wobble
or come off the bike and cause damage on the bike and serious injuries to the cyclist, including death.
It is therefore essential that:
1. Be sure to learn how to securely install and remove the wheels.
2. Understand and apply the correct technique for holding the wheel in place with a quick opening sys-
tem.
3. Each time you ride the bike check if the wheel is securely fastened.

The derailleur system includes the front and rear
derailleurs, the shift levers, and the derailleur con-
trol cables, all of which must function correctly for
smooth gear shifting to occur. There are several dif-
ferent types of derailleur systems but all operate us-
ing similar principles. For the rear shifter, there will
STRETCH PREVIOUSLY THE
be a positive "click" for each gear.
DERAILLEUR CABLES TO PREVENT
THEM FROM BECOMING WEARY
When properly adjusted, one click should change
one gear at a time. For the front shifter (if equipped)
some shifters are a "friction" system, where you
move the shifter until the desired shift occurs. Oth-
ers have the same audible "click" to indicate that one
gear has been changed. The adjustments are similar.
