Derailleur adjustment
If the chain of your bicycle falls off at the largest COG/sprocket or the chain is having problems remaining on the
correct gear, you may need to adjust your derailleur.
There are a multiple ways to adjust your derailleur but for a simple adjustment on the changing of gears, follow
these instructions.
Locate at the rear of the derailleur, the adjusting knob where the cable enters the derailleur. This knob
allows the loosening or tightening of the cable. Rotate this knob clockwise or counterclockwise until the
derailleur is properly changing gears. This is a quick fix but for a correct adjustment, the adjustment should
be at the cable locking plate and fixing bolt with the knob used for fine tuning.
For a more detailed adjustment of the derailleur, you should bring your bicycle to an authorized Prodeco dealer or a
neighborhood bike shop who services Shimano derailleurs.
Your derailleur also includes a Tensioning Adjustment and Stroke Adjustment. Below is Shimano’s documentation
on making these adjustments:
