WARNING
• Obtain and read the service instructions carefully prior
to installing the parts.
Loose, worn, or damaged parts may cause injury to the
rider. We strongly recommend only using genuine
Shimano replacement parts.
• Obtain and read the service instructions carefully prior
to installing the parts.
If adjustments are not carried out correctly, the chain may
come off and this may cause you to fall off the bicycle
which could result in serious injury.
• Be careful not to let the cuffs of your clothes get caught in
the chain while riding, otherwise you may fall off the
bicycle.
• Read these Technical Service Instructions carefully, and
keep them in a safe place for later reference.
Be sure to follow the sequence described below.

• If gear shifting operations cannot be carried out smoothly,
clean the derailleur and lubricate all moving parts.
• If the amount of looseness in the links is so great that
adjustment is not possible, you should replace the
derailleur.
• When the chain is in the position shown in the illustration,
the chain may contact the front chainrings or front
derailleur and generate noise.
If the noise is a problem, shift the chain onto the nextlarger rear sprocket or the one after.

Tightening torque:
5 - 7 N·m
{44 - 60 in. lbs.}
• For smooth operation, use the specified outer casing and
the bottom bracket cable guide.
• Grease the inner cable and the inside of the outer casing
before use to ensure that they slide properly.
• This front derailleur is for triple front chainwheel use only.
It cannot be used with the double front chainwheel, as the
shifting points do not match.
• For the chain, be sure to use only the Shimano 10-speed
super-narrow type of chain. The wide type of chain cannot
be used.
• Parts are not guaranteed against natural wear or
deterioration resulting from normal use.
• For maximum performance we highly recommend
Shimano lubricants and maintenance products.
• For any questions regarding methods of installation,
adjustment, maintenance or operation, please contact a
professional bicycle dealer.

In the case of carbon frames, it may be necessary to
lower the tightening torque in order to prevent damage
to the frame. Please consult the bicycle or frame
manufacturer regarding the appropriate level of
tightening torque for carbon frames.

While turning the crank arm, gently operate lever (b) and check that
the front derailleur moves slightly toward the smallest chainring. If the
front derailleur moves by a large amount and the chain is set onto the
smallest chainring at this time, loosen the top adjustment bolt by 1/8th
of a turn. Then, after returning the
chain to its original position, adjust
and check the trimming mechanism.

Note
Note: There are 2 derailleur positions for the intermediate chainring. When
making the cable adjustment, make sure that the derailleur is in the
inner side (toward small chainring) of the two positions. Locate the
derailleur to this position by shifting from the largest to the
intermediate chainring (recommended) or by shifting from the small to
the intermediate chainring, then gently press lever (b) until a small
click is felt (to position the derailleur to the inner side of the
intermediate chainring).
4. Cable adjustment using the intermediate
chainring
When making the cable adjustment, place the chain
on the largest sprocket for the rear and the middle
chainring for the front.
If the chain falls to the crank side
Tighten the top adjustment screw
clockwise (about 1/4 turn).
If shifting is difficult from the intermediate
chainring to the largest chainring
Loosen the top adjustment screw
counterclockwise (about 1/8 turn).
If shifting is difficult from the intermediate
chainring to the smallest chainring
Loosen the low adjustment screw
counterclockwise (about 1/8 turn).
If there is interference between the chain
and the front derailleur outer plate at the
largest chainring
Loosen the top adjustment screw
counterclockwise (about 1/8 turn).
If the intermediate chainring is skipped
when shifting from the largest chainring
Loosen the outer casing adjustment
barrel counterclockwise (1 or 2 turns).
If there is interference between the chain
and front derailleur inner plate when the
rear sprocket is shifted to the largest
sprocket when the chainwheel is at the
intermediate chainring position.
Tighten the outer casing adjustment
barrel clockwise (1 or 2 turns).
If the chain falls to the bottom bracket
side.
Tighten the low adjustment screw
clockwise (about 1/8 turn).
If there is interference between the chain Loosen the low adjustment screw
and the front derailleur inner plate when
counterclockwise (about 1/8 turn).
the chain is on the smallest chainring and

Be sure to read these service instructions in conjunction with the service
instructions for the ST-5600 before use.
