Derailleur System
The derailleur system includes front and rear derailleurs, shift levers,
and derailleur control cables. For smooth shifting, all components
must function properly.
Although the front and rear derailleurs are initially adjusted in the
factory, you need to inspect them before each ride.
To begin, twist the shifter to the largest number indicated, and the
cable shall loosen the anchor bolt on the rear derailleur, placing the
chain on the smallest sprocket. Adjust the high limit screw so that
the guide pulley and the smallest sprocket are lined up vertically.
Re-tighten the cable, pull out any slack, and re-tighten the anchor
bolt securely. Shifting through the gears, making sure that each gear
is achieved quietly and swiftly.
If necessary, use the barrel adjuster to fine tune the cable tension by
turning it the direction you want the chain to go. For example,
turning clockwise loosens cable tension and moves the chain away
from the wheel, while turning counter-clockwise tightens cable
tension and direct the chain towards the wheel.
