CHANGING GEARS
Introduction on derailleur
The front and the rear derailleur have already been
adjusted by your Scott dealer. Therefore, no readjust-
ment will be necessary to begin with. However, it is
advisable to check the adjustment of the gear change
mechanism regularly.
When the gear lever is fully pushed towards the front,
the chain should be below the smallest or the biggest
sprocket.
When the adjustment of the derailleur is inaccurate, for
example when the chain is a little slack, it can jump off
either between the biggest sprocket and the spoke on
the left side and/or between the smallest sprocket and
the frame on the right side. This can lead to severe
damages and/or a fall.
The adjustment of the rear derailleur must not be too
slack (causing the chain to derail), nor too tight. In the
latter case, chain noise occurs when the chain is on the
smallest or largest sprocket. The stroke of the derailleur
can be limited both on the left and the right side by
means of two limit screws.

ADJUSTMENT OF THE INDEX
REAR DERAILLEUR
All Scott bikes are fitted with a so-called index rear
derailleur. This derailleur can be positioned exactly
below the required sprocket through pre programmed
"clicking". Changing gears is easy with the index sys-
tem, provided it is properly adjusted. Contrary to the
adjustment of any ordinary derailleur, the adjustment of
the index derailleur requires special attention and is
therefore best left to your Scott dealer. Should you
nevertheless want to adjust the index system yourself,
proceed as follows:
1. Change to the largest gear (smallest rear sprocket).

Turn the top adjustment screw
to adjust so that the guide pul-
ley is in line with the outer line

2. Drive the pedals forward a few times. In case of
chain noise, adjust the derailleur with the adjusting
screws.
3. Pull the derailleur control cable tight and secure it
with the cable screw in the rear derailleur to tighten
the cable screw even further.
4. Use the shift lever to change to the next sprocket.
There should be no chain noise. If necessary, adjust
the cable screw.

ADJUSTMENT OF THE FRONT
DERAILLEUR
Usually, the front derailleur is secured to the seat tube
with a clamping strip, fitted with a bolt. As a result the
derailleur can be moved up/down and turned, the front
derailleur can be adjusted in such a way that the chain
does not derail when the derailleur is in its highest posi-
tion. The derailleur should not protrude beyond the lar-
gest chain wheel by more than 2 mm and must not touch
the pedal crank. For correct adjustment proceed as fol-
lows.
