If noises cannot
be heard:
Turn the screw anticlockwise until the chain rubs

The adjustment screw may also be on the shiing
lever or on the ame.
Once the slack in the shiing cable
has been taken up by the shiing
lever, the chain should ideally rub
the third sprocket and produce a
noise.
Release the shiing lever in second
gear and turn the crank.
If the chain rubs the third sprocket, turn the adjustment
screw clockwise slightly until the grinding noise stops.
To ensure problem-ee SIS operation, you will need to
lubricate all power-transmitting parts.
If the chain is in the position shown, it could rub
against the chainrings or the ont derailleur and
make a noise. If this is the case, you can shi the
