Lever
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 shift 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 shifting
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 front derailleur producing a char-
acteristic noise. When this happens, press lever b lightly
to the point where it clicks, this causes the front derailleur
to move slightly towards the smaller chainring, thereby
eliminating the noise.
Twist-grip shifters
To shift up or down one gear only, turn the twist-grip shift-
er by one increment forwards or backwards.
