Operation And Control - Scott TIME TRIAL MACHINE Owner's Manual

SAFETY INSTRUCTIONS
Read in any case carefully the manual of the gear manufacturer. Make your-
self familiar with your new gears in an area free of traffic, if necessary. If you
are in doubt or if you have any questions, contact your SCOTT dealer.

Operation and control

Derailleur gears always work according to the following principle:
Large front chainring
Small front chainring
Large rear sprocket
Small rear sprocket
Normally, the shifters are mounted as follows:
Shift lever right – rear sprockets
Shift lever left
Modern SCOTT road bikes can have up to 33 gears. As there are, however,
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.
The chain runs unfavourably when the smallest chainring is used with one of the
two or three outermost (smallest) sprockets (a) or when the largest chainring is
used with one of the inmost (largest) sprockets (b).
The bottom bracket is the interface between cranks and frame. There are dif-
ferent 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
forcefully. It must be absolutely free of play. If you notice any play, contact your
SCOTT dealer immediately.
