• The upper wheel must be at the cor
-
rect distance from the largest sprocket
(Fig.21).
• The MAXIMUM distance between the
tip of the teeth of the upper wheel and
the tip of the teeth of the largest sprocket
must be MAX 3 mm.
• The MINIMUM distance is the point at
which, when the rear derailleur is ope
-
rated, this makes a noise because the
wheel is too close to the sprockets.
MAX. 3 mm MIN. noise

• Position the chain on the 5TH sprocket
counting from the smallest.
• Turn the cable tension adjuster (
E -
Fig.
22) until perfect alignment is obtained
between the centreline of the top roller
and the centreline of the 5TH sprocket.
• If centering between the centrelines of
the roller and the fourth sprocket is not
correct, turn the adjuster (
E -
Fig. 22)
counterclockwise to shift the rear derail
-
leur inwards. Turn clockwise to shift the
rear derailleur outwards.
• Check that when the shifter is actuated
accordingly, the rear derailleur positions
the chain on the largest sprocket; if this
does not occur, turn the screw (Fig. 23)
repeatedly (slackening it until the chain
is positioned on the largest sprocket
without overshifting).

an accident, personal injury or death.
