DETAILED MAINTENANCE
Adjustment - Front Derailleur
1. Shift the rear shifter to the smallest number indicated,
then shift the front shifter to the smallest number
indicated. Disconnect the front derailleur cable from the
cable anchor bolt and place the chain on the smallest
chainwheel.
2. Make sure the front derailleur cage is parallel with the
outer chainwheel on the crankset. There must be a
3 - 5 mm gap between the bottom of the derailleur cage
and the top of the outer chainwheel teeth to ensure the
derailleur will clear the chainwheel when shifting.
3. Adjust the low limit screw so the chain is centered in the
middle of derailleur cage. Pull all slack out of the cable by
pulling it taut, then reconnect the cable and tighten the
cable anchor bolt securely.
4. Shift the front shifter into the largest gear and pedal the
bike so the chain jumps to the largest chainwheel. If the
chain does not shift onto the largest chainwheel, you will
need to turn the High limit screw counterclockwise until
the chain moves to the largest chainwheel. If the chain
falls into the pedals, the High limit screw has been turned
too far. You will need to readjust the High screw clockwise
in 1/4 turn increments. until the chain no longer falls off.
5. Shift through each gear ensuring all are achieved quietly
and without hesitation.
6. Some shifters may have an adjusting barrel. Use the
adjusting barrel to fine tune the adjustment of the chain
location. Turn the adjusting barrel clockwise will move the
derailleur inboard - towards the frame, while turning it
counterclockwise will direct the chain outboard - away
from the frame.
