CHAPTER THREE
Inspection, Adjustment & Lubrication
Derailleur Shift Systems
To adjust the high gear position of the rear
derailleur
1. Shift the chain onto the smallest rear cog and
the largest front chainring.
2. Loosen the cable clamp bolt (Figure 3.4.2) until
the cable is free.
3. Stand behind the bicycle to see that the smallest
rear cog, the chain, and the two derailleur
pulleys are in line.
4. If they are not aligned, turn the high gear
adjusting screw (usually marked “H”, Figure
3.4.7) until this line is established.
5. While pulling on the cable, up-shift until the
shifter is in the small cog position.
6. Turn the adjusting barrel on the shifter, or
down tube, all the way clockwise. Turn the
adjusting barrel on the rear derailleur all the way
clockwise, and then one turn counter-clockwise.
7. Insert the cable into the clamp bolt groove on
the rear derailleur, pull the shift cable taut, and
clamp the cable:
• Rear derailleur cable clamp bolt: 44-60 lb•in (5.0-6.8 Nm).
To adjust the low gear position of the rear derailleur
1. Turn the low gear adjusting screw on the rear
derailleur (usually marked “L”, Figure 3.4.8)
far enough counter-clockwise so that it will not
restrict the movement of the derailleur.
2. Carefully shift the chain onto the smallest front chainring
and the largest rear cog. Do not over-shift the rear derail-
leur, or the chain may wedge between the large cog and the
spokes.
3. Position the rear derailleur pulleys in line with the largest cog.
4. Turn the low gear adjusting screw clockwise until it meets
4. 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.
5. Go through the various gear combinations. Make sure the
chain does not fall off when you shift.
To align the indexing system of the rear derailleur
1. Shift the chain onto the largest front chainring and the
smallest rear cog.
