Trimming operation
When lever b is operated, there is one click where trim-
ming (the noise prevention mechanism) engages, and a
second stronger click when the gear shi stroke is com-
plete. The noise prevention mechanism no longer clicks
once the trimming operation is complete which means
that only the click-in positions will be heard when shiing
between sprockets.
Chain position
Front derailleur movement
If the chain is on the large chainring and the large sprock-
et, the chain will rub the ont derailleur producing a char-
acteristic noise. When this happens, press lever b lightly
to the point where it clicks, this causes the ont derailleur
to move slightly towards the smaller chainring, thereby
eliminating the noise.
Twist-grip shiers
To shi up or down one gear only, turn the twist-grip shi-
er by one increment forwards or backwards.
