Derailleur

Although the front and rear derailleurs are initially adjusted at

the factory, you will need to inspect and readjust both before

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 loos-

en 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.
