The gear shift cable connects the shifter to the front or rear derailleur of the bicycle.
- Signs of wear: gears shift with a delay, the chain does not land on the right sprocket, the shifter feels stiff.
- The cable is threaded through the shifter and the housing, the excess is cut off and the end is capped with a ferrule.
After installation the derailleur needs adjusting: set the end positions and the cable tension with the barrel adjuster.
