chainring to a larger one by moving the left-hand shifter forward. You will learn soon what positions should be used for different riding
conditions. You will learn it through training only. Do not try to change gears while applying heavy pressure on the pedals. Never pedal
backward when changing gears. This could result in the chain slipping down.
Recommendation: Do not use combinations of gears at which excessive chain crossing occurs. The complete gear-changing
mechanism suffers from it.
FRONT DERAILLEUR
• The chain guide should be aligned in line with the chainrings and should be 1-3 mm above the teeth of the largest chainring.
• If the front derailleur shifter (the left-hand one) is in the back position, check to ensure that the gear changing cable is not
slackened excessively. The play can be eliminated by loosening the screw with the cable anchor, pulling the cable with pliers and
retightening the screw.
• If the chain slips down from the largest chainring
towards the right-hand crank, tighten the top
adjustment front derailleur screw with one or two
turns. Test the gear changing and adjust again, if
necessary.
REAR DERAILLEUR
• Lift the back wheel. While turning the crank, pull the right-hand shifter back. The chain should be positioned on the smallest
cog. If this is not the case, continue turning the crank and loosen the top adjustment screw of therear derailleur until the chain is
on the smallest cog.
• While turning the crank, pull the shifter forwards completely until the chain is shifted to the second smallest cog. Pull the
right-hand shifter back, the chain should be shifted smoothly on the smallest cog. - While turning the crank, pull the shifter
forwards completely. The chain should be positioned on the largest rear cog. If this is not the case, continue turning the crank
and turn the bottom adjustment screw of the rear derailleur until the chain is on the largest cog.
• While turning the crank, pull the shifter back slightly until the chain is on the second largest cog. Pull the shifter fully forward,
the chain should be shifted smoothly to the largest cog.
CAUTION: For bikes provided with the index gear changing system, see the adjustment procedure recommended
by the manufacturer.
CABLE ADJUSTMENT
• Cable stretching may appear and
cause incorrect gear changing.
Cable stretching appears if a cable
is slackened (when the shifters are
pulled fully back). You can eliminate
slackening if you loosen the cable
locking screw, pull the cable out
firmly and retighten the locking
screw..
