Adjustment – Front Derailleur
the front derailleur must be positioned so that it’s chain guides are parallel to the chainrings. the
outer chain should have clearance of about 2-4mm above the large chainring when directly over it.
alter the derailleur position after loosening the clamp bolt.
to adjust low gear, shift the chain onto the smallest front chainring and the largest rear sprocket,
and loosen off the control cable fixing bolt. Turn the adjusting screw marked “L” until the inner
cage just clears the chain.
With the shift lever fully in the low position, pull the control cable taut and re-tighten the cable
fixing bolt.
to adjust high gear, shift the chain to engage the smallest rear sprocket, and turn the adjusting
screw marked “H” so that the chain can be shifted to the largest chainring. Position the derailleur
so that the inside of the outer cage just clears the chain by turning the “H” adjusting screw further.
test the gears in all possible front and rear chain positions. If the chain rubs against the cage
when on the inner or outer chainring in any rear sprocket position, then turn the appropriate
adjusting screw counter-clockwise. If the chain falls off either the inner or outer chainring, turn
the appropriate adjusting screw clockwise. If the chain will not shift onto either the inner or outer
chainring, turn the appropriate adjusting screw counter-clockwise.
to fine tune the adjustment on MtB bicycles fitted with front sIs, shift the chain to the largest
rear sprocket and the largest front chainring. shift from the largest to the middle chainring.
turn the cable adjusting barrel, located in the shifter, so that the inner chainguide just clears the
chain. this should complete the adjustment so that the chain can shift cleanly, without hesitation
between each chainring.
Fine tuning on racing style bicycles fitted with dual control (STI) levers is done by first shifting the
chain to the largest sprocket and largest chainring. Next, push the left hand inner lever lightly to
engage noise prevention mechanism.

about 2-4mm above the large chainring when directly over it.
Alter the derailleur position after loosening the clamp bolt.

and the largest rear sprocket, and loosen off the control cable fixing bolt.
Turn the adjusting screw marked ‘L’ until the inner cage just clears the chain.

To adjust high gear, shift the chain to engage the smallest rear sprocket,
and turn the adjusting screw marked ‘H’ so that the chain can be shifted to
the largest chainring. Position the derailleur so that the inside of the outer
cage just clears the chain by turning the ‘H’ adjusting screw further.
Test the gears in all possible front and rear chain positions. If the chain
rubs against the cage when on the inner or outer chainring in any rear
sprocket position, then turn the appropriate adjusting screw counter-
clockwise. If the chain falls off either the inner or outer chainring,
turn the appropriate adjusting screw clockwise. If the chain will not shift onto
either the inner or outer chainring, turn the appropriate adjusting screw
counter-clockwise.
To fine tune the adjustment on MTB bicycles fitted with front SIS, shift the
chain to the largest rear sprocket and the largest front chainring. Shift from
the largest to the middle chainring. Turn the cable adjusting barrel, located in
the shifter, so that the inner chainguide just clears the chain. This should
complete the adjustment so that the chain can shift cleanly, without
hesitation between each chainring.
