Trimming (noise prevention)
Depending on the position of the chain after shifting, it
may rub against the outer chain guide plate or inner chain
guide plate of the front derailleur and produce noise. In
this case, lightly press lever a or lever b to move the front
derailleur until it is no longer in contact with the chain.
This procedure is known as "trimming". Trimming is pos-
sible if the chain is on the large, intermediate or small
chainring.
If you perform the trimming operation at one of the fol-
lowing positions, the noises will disappear completely.
