DERAILLEUR SYSTEMS
The derailleur system includes the front and rear derailleurs, the shift levers, and
the derailleur control cables, all of which must function correctly for smooth gear
shifting to occur. There are several different types of derailleur systems but all
‘friction’ type system where you will need to feel each gear shift into position.
position to a positive click mechanism in the shifter, and makes shifting very
simple and precise.
INSPECTION
The operation of the derailleur system should be checked at least every month.
The rear derailleur
should shift the chain cleanly from one cog to the next without hesitation. On
Index System equipped bicycles, 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. 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 anytime. 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
