Optimum adjustment
Once the slack in the shifting cable
has been taken up by the shifting
lever, the chain should ideally rub
the third sprocket and produce a
noise.
Release the shifting 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-free 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 front derailleur and
make a noise. If this is the case, you can shift the
chain onto the second or next largest sprocket.
