Operation and control
Derailleur gears always work according to the following principle:
Large front chainring
– high/heavy gear
– higher gear ratio
Small front chainring
– low/easy gear
– lower gear ratio
Large rear sprocket
– low/easy gear
– lower gear ratio
Small rear sprocket
– high/heavy gear
– higher gear ratio
Normally, the shifters are mounted as follows:
Shift lever right – rear sprockets
Shift lever left – front chainrings
Modern SCOTT city/trekking bikes can have up to 30 gears. As there are, how-
ever, overlapping ranges, actually 15 to 18 gears are usable. It is not advisable to
use gears which involve an extremely oblique run of the chain, as this reduces
power transmission efficiency and hastens wear of the chain.
An unfavourable run of the chain is when the smallest chainring is used with
one of the two or three outermost (smallest) sprockets
(c)
or when the largest
chainring is used with one of the inmost (largest) sprockets
(d)
.
The bottom bracket
(e)
is the interface between cranks and frame. There are
different designs, in some cases the bearing spindle is part of the bottom
bracket, in some other cases it is integrated into the right crank. Sealed bottom
brackets are maintenance free and delivered without play ex works. The bottom
bracket in the frame must be checked for play at regular intervals.
Also check at regular intervals whether the cranks are firmly attached to the
bearing spindle or whether there is play. Grab the crank and try to jiggle it force-
fully. It must be absolutely free of play
(f)
. If you notice any play, contact your
SCOTT dealer immediately.
GEARS
DERAILLEUR GEARS
The gears of your SCOTT bike
(a+b)
serve to adjust the gear ratio to the terrain
you are riding on and the desired speed.
A low gear (where in the case of derailleur gears the chain runs on the small
chainring and a large sprocket) allows you to climb steep hills with moderate
pedalling force. You must, however, pedal at a faster pace. High gears (large
chainring, small sprocket) are for riding downhill. Every turn of the pedals takes
you many metres forward at correspondingly high speed.
DANGER!
G
Continue pedalling at reduced cadence during gear shifting, however, at
clearly reduced pedalling force. In particular when shifting through the
chainrings continue pedalling slowly and without force.
DANGER!
H
With SCOTT pedelecs reduce the cadence and the pedalling force short-
ly before you start shifting. In doing so there is a short interruption of the
drive. If you continue pedalling, the high chain forces could result in a chain
failure.
CAUTION!
A
Practise switching gears in a place free of traffic until you are familiar with
the functioning of the levers or twist grips of your SCOTT bike.
NOTE!
U
SCOTT pedelecs have only one chainring. As a consequence there is no
front derailleur and no shifter on the left handlebars.
NOTE!
I
Read the gear manufacturer’s manual on this SCOTT info CD carefully and
practise shifting gears until you are familiar with it before you set off for the
first time.
