To make the low gear adjustment on the rear derailleur, first turn the low gear adjusting

screw (usually marked “L”) far enough counter-clockwise so that it will not restrict the

movement of the derailleur. While pedaling the bicycle with your hand, carefully shift the

chain onto the smallest front chainring and the largest rear cog. Do not over-shift the

rear derailleur, or the chain may wedge between the large cog and the spokes. Position

the rear derailleur pulleys in line with the largest cog. Turn the low gear adjusting screw

clockwise until it meets resistance. If you have turned it too far, the derailleur will move

toward the outside of the bicycle. Go through the various gear combinations. Make sure

the chain does not fall off when you shift.

To align the indexing system of your rear derailleur, shift the chain onto the largest

front chainring, and the smallest rear cog. Rotate the shifter to shift the chain onto the

next smallest rear cog. If the chain makes excessive noise or does not shift, rotate the

rear derailleur barrel adjuster counter-clockwise (increasing cable tension) to align the

derailleur pulleys with this second cog. Do this in small increments, until the system shifts

smoothly and quietly. If making this adjustment makes the chain shift to the third smallest

cog, derailleur cable tension is too great. Rotate the barrel adjuster clockwise until the

derailleur pulleys and the second smallest cog is aligned. Go through the various gear

combinations to ensure that the chain smoothly lines up with all the rear cogs.

If the cable of either derailleur fails the previous Inspection, do not ride the bicycle until

the cable has been replaced. Inspect the housings. If they are damaged or rusty, replace

them as well. If you replace any housings, make sure that the pieces are cut to proper

length and of the correct type of housing (use the old pieces as guides) and that the

housing ends are free of burrs; the cable should pass freely through these ends.

To install a new derailleur cable in a Twist shifter, shift the chain to the smallest rear

cog and smallest front chainring. Loosen the derailleur cable clamp bolt on the derailleur

and note the path the cable follows.

Remove the cable through the shifter. Open the small cable window on the shifter

(denoted by a small ‘door’) to expose the leaded end of the cable.

Install the new cable by threading the cable through the shifter. Apply Wrench Force

synthetic grease or similar lubricant to the new cable and feed it through all of the cable

guides, housings and the cable clamp following the path of the old cable. Reattach and

adjust the derailleur cable as explained in Adjustment. After you have done this, cut the

cable so that there is no more than 2 inches (51 mm) of cable length exposed beyond the

cable clamp bolt. To prevent fraying of the cable end, crimp on a metal cap or apply some

solder to the end of the cable.
