DERAILLEUR
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 to chain to go. For example, 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.

Front Derailleur
Shift both shifters to the smallest number indicated and place the chain
on the corresponding cog and chainwheel. Disconnect the front derailleur
cable from the cable anchor bolt. Check the position of the front derailleur; it
should be parallel with the outer chainwheel and clear the largest chainwheel
by 3-5mm when fully engaged.
With the chain on the smallest chainwheel in front and the largest cog
in back, adjust the Low limit screw so the chain is centered in the front
derailleur cage. Reconnect the cable, pull any slack out, and tighten the
anchor bolt securely. Shift the front shifter to the largest chainwheel. If the
chain does not go onto the largest chainwheel, turn the high limit screw in
1/4 turn increments counter-clockwise until the chain engages the largest
chainwheel. If the chain falls off the largest chainwheel, and into the pedals,
you will need to turn the High limit screw in 1/4 turn increments clockwise
until the chain no longer falls off. Shift through every gear, using the barrel
adjusters to fine-tune each transition. The barrel adjuster for the front
derailleur is located on the front shifter where the cable tension and direct
the chain closer to the frame while counter-clockwise will tighten the cable
tension and direct the chain away from the frame.
Do not ride a bicycle that not shifting properly.
Overlooking proper adjustments may cause irreparable
damage to the bicycle and/or bodily injury.
