Operation:
Operate the shift system as follows:
1.The rider turns the rear shift control around the handlebar (for twist shift models) or moves the shift lever (thumb shift models) to an index position
2.When the rear shift control moves into each position with a “click” sound, the shift is complete
3.The shift control pulls a cable wire that is attached to the rear derailleur.
4.The derailleur moves and guides the chain from one sprocket to another.
5.If there is some chain noise after the shift, turn the rear shift control a small amount to “trim” the rear derailleur.
