Instruction manual

Trimming (noise minimisation)
Depending on the chain position after completion of shifting, the chain may rub
against the outer or inner chain guide plate and cause noises. In this case, press
lever ‘a’ or lever ‘b’ lightly in order to move the derailleur slightly so that it no
longer contacts the chain.
This adjustment is called ‘trimming’. Trimming is possible when the chain is
located on the large, middle or small chain sprocket. If noises occur, trim to one
of the following positions in order to completely eliminate the noises.
