WARNING: This is a general guide. If you are unfamiliar with derailleur tuning we strongly recommend you take your bike
to your dealer for professional service, to avoid damage to the bike.
Adjust the lower adjustment screw to make the guide wheel move to the smallest sprocket on the free-wheel. Align the
centre of the guide pulley and the outer line of the smallest sprocket, then tighten the gear shift cable with the nut on the
derailleur.
Turning the front chain-wheel, with the rear wheel off the ground, operate the gear lever to shift to the largest sprocket.
Turn the upper adjustment screw so that the guide pulley moves to a position directly below the largest sprocket.
By turning the screw inwards you shorten the travel of the derailleur, moving the guide pulley towards the centre of the free
wheel. By turning the screws outwards you increase the travel of the derailleur towards the frame or the spokes. When the
stop screws are adjusted correctly the chain will not come off the smallest cog into the frame or off the largest cog and into
the spokes.
Once the stop screws are correctly adjusted the cable tension can be adjusted by turning the barrel nut on the derailleur
cable entry point until the gears operate smoothly when selected with the gear lever.
