DETAILED MAINTENANCE
Lubrication
All the pivoting points of the front and rear derailleurs should be lubricated
with light oil at least every month. Be sure to wipe off any excess oil to
prevent attraction of dirt into the mechanisms. The shifting cables should
be cleaned and re-coated with a thin layer of grease every six months, or
whenever new cables are being installed.
Adjustment – Rear Derailleur
The Low limit screw determines how far the rear derailleur will travel
toward the wheel of the bicycle, while the High limit screw determines how
far the cage will travel toward the frame.
1. Shift the rear shifter to the largest number indicated, disconnect the
rear derailleur cable from the cable anchor bolt and place the chain on
the smallest sprocket.
2. Adjust the High limit screw so that chain and the smallest sprocket
are lined up vertically. Remove any slack in the cable by pulling it taut,
then re-connect the cable and tighten the cable anchor bolt securely.
3. Shift up through the gears makes sure that each gear is achieved
quietly and without hesitation.
If noise occurs, use the barrel adjuster to fine-tune the cable tension.
Turning the barrel adjuster clockwise will decrease cable tension and
allow the derailleur cage to move farther away from the bicycle in
small increments. Turning counter-clockwise will increase cable
tension and bring the cage closer to the bicycle. This will micro-adjust
the positioning of the derailleur cage in relation to the freewheel.
4. Shift the chain onto the largest sprocket; adjust the low limit screw so
the chain and the largest cog are lined up vertically. If you are unable
to get the chain and the largest cog, turning the Low limit screw
counter-clockwise will enable the chain to move towards the wheel.
5. Shift through the gears ensuring each gear is achieved quietly and
without hesitation.
NOTE: It may take several adjustments to achieve the desired positioning.
