CHAPTER THREE
Inspection, Adjustment & Lubrication
shifted, the front derailleur should shift the chain from a larger
chainring to a smaller one. When up-shifted, the derailleur
should shift the chain from a smaller chainring to a larger one.
After the shift, by moving the shifter slightly, you should be
able to position the front derailleur such that it does not rub on
the chain. The chain should not fall off the inner-most or outer-
most chainrings at any time.
Once a month
check the operation of the right shift levers/
rear derailleur. When down-shifted, the rear derailleur should
shift the chain from a smaller cog to a larger one. When up-
shifted, the rear derailleur should shift the chain from a larger
cog to a smaller one. After the shift, the rear derailleur should
be positioned such that the chain runs smoothly without
jumping. The chain should not fall off the inner-most or outer-
most cogs at any time.
Adjustment
Derailleur adjustment should be done with the bike held firmly
in a workstand, or with someone holding the rear wheel off
the ground, such that the drivetrain and shift system can be
operated while the bike remains stationary.
To adjust the low gear position of the front derailleur
1. Shift the chain onto the smallest front chainring and the
largest cassette cog.
2. Loosen the front derailleur cable clamp bolt (Figure 3.4.1)
until the cable is free.
3. Turn the low gear adjusting screw (marked “L”, Figure
3.4.5) until the inner chain guide of the derailleur is
approximately 0.5 mm from the chain.
4. Pull on the cable end, and down-shift the left shift lever
several times so it is in the small-chainring position.
5. Turn the shift cable adjusting barrel to its most clockwise
position.
6. Insert the cable in the groove found next to the derailleur
cable clamp bolt, pull the cable taut, and clamp the cable:
• Front derailleur cable clamp bolt: 44-60 lb•in (5.0-6.8 Nm).
To adjust the high gear position of the front derailleur
1. Shift the rear derailleur to the smallest rear cog.
2. Turn the high-gear adjusting screw (marked “H”, Figure
2. Turn the high-gear adjusting screw (marked “H”, Figure
3.4.6) counter-clockwise until it cannot interfere with the
motion of the derailleur.
