    • Fine tune the derailleur by tightening or loosening the barrel adjuster screw. Loosening this screw causes the derailleur to move slightly towards a larger sprocket, while tightening it moves the derailler towards a smaller sprocket.

    • Shift through each gear while pedaling. The derailleur should move the chain one gear over each time you shift up or down.

    • If the chain skips or makes noise when you are not shifting, use the barrel adjustment screw to fine tune the derailleur alignment.

    • Repeat the previous steps until the derailleur shifts smoothly and makes a minimal amount of noise.

Conclusione

For future adjustments it is likely that you will only need to adjust the barrel adjuster screw for fine adjustment.
