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 rider turns the front shift control around the handlebar (for twist shift models)
or moves the shift lever to an index position (thumb shift models)
4. Each shift control pulls a cable wire that is attached to the derailleur.
5. The derailleur moves and guides the chain from one sprocket to another.
6. If there is some chain noise after the shift, turn the rear shift control a small
amount to “trim” the rear derailleur.
