Optimum adjustment
Once the slack in the shiing cable
has been taken up by the shiing
lever, the chain should ideally rub
the third sprocket and produce a
noise.
Release the shiing 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
chain onto the second or next largest sprocket.
