• It can move 18 steps inward and 18 steps outward from the initial position, for a
total of 37 positions.
• In adjustment mode, the chain guide will overrun slightly and then move back in
an exaggerated manner so that you can check the adjustment direction. When
checking the positions of the chain guide and the chain, perform the check when
the front derailleur has come to a stop.
