If the chain is on the large chain ring and the large
sprocket, the chain will rub the front derailleur producing
a characteristic noise. When this happens, press lever
b lightly to the point where it clicks, this causes the front
derailleur to move slightly towards the smaller chain ring,
thereby eliminating the noise.
XI-2.2: Twist-grip shifters
To shift up or down one gear only, turn the twist-grip shifter by one increment forwards or back-
wards.
If you wish to shift up or down several gears at once, continue turning the shifting lever by the
required number of shift positions and in the required direction.
XI-3. Rear derailleur
NOTE: Have your specialist cycle shop carry out maintenance on the derailleur gears, or re-
place or adjust them.
XI-3.1: Precision adjustment/rear derailleur
Operate the shifting lever to shift the chain from the smallest sprocket to the second sprocket.
Then take up the slack in the shifting cable with the shifting lever and tum the crank.
Turn the screw anticlockwise until the chain rubs against the third sprocket.
NOTE: The adjustment screw may also be on the shifting lever or on the frame.
Once the slack in the shifting cable has been taken up by the shi ing 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 frie grinding noise stops.
To ensure problem-free SIS operation, you will need to lubricate all pow-
er-transmitting parts.
