Although the front and rear derailleurs are initially adjusted at
the factory, you will need to inspect and readjust both prior to
riding the bicycle.
Rear Derailleur
Begin by shifting the rear shifter to largest number indicated,
disconnect the cable from the rear derailleur cable anchor bolt,
and place the chain on the smallest sprocket.
Adjust the High limit screw so the guide pulley and the
smallest sprocket are lined up vertically. Reconnect the cable,
pull out any slack, and retighten the anchor bolt securely. Shift
through the gears, making sure each gear achieved is done
quietly and without hesitation. If necessary, use the barrel
adjuster to fine tune each gear by turning it the direction you
want the chain to go. For example, turning clockwise will
loosen the cable tension and move the chain away from the
wheel, while turning counter-clockwise will tighten cable
tension and direct the chain towards the wheel. Shift the rear
shifter to the gear one and place the chain on the largest cog.
Adjust the Low limit screw in quarter turn increments until the
guide pulley and the largest cog are aligned vertically. Again,
shift through each gear several times, checking that each gear
is achieved smoothly. It may take several attempts before the
rear derailleur and cable is adjusted properly.
Ensure all bolts are secured tightly and the chain
does not fall off in either direction.
