SIS adjustment
1. Low adjustment
WARNING
• Obtain and read the service instructions carefully prior to installing the parts.
Loose, worn or damaged parts may cause the bicycle to fall over and serious injury
may occur as a result. 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.
Set so that the clearance between the chain guide inner
plate and the chain is 0 - 0.5 mm.

Note
• 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,
Front
the chain may contact the front chainrings or front derailleur
chainrings
and generate noise. If the noise is a problem, shift the chain
onto the next-larger rear sprocket or the one after.
• For smooth operation, use the specified outer casing and

sprockets
• Grease the inner cable and the inside of the outer casing
before use to ensure that they slide properly.
• 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.
2. Connection and securing of cable
While pulling the inner cable, tighten the wire fixing bolt with a 5 mm
allen key to secure the cable.
Tightening torque:
6 - 7 N·m {52 - 60 in. lbs.}
After taking up the initial slack in the cable,
re-secure to the front derailleur as shown in
the illustration.

While turning the crank arm, gently operate lever (b) and check that the front derailleur
moves slightly toward the small chainring. If the front derailleur moves by a large
amount and the chain is set onto the small 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.
Clearance:
0 - 0.5mm
(3) After trimming, adjust the clearance
(by using the cable-adjustment bolt)
of the chain and chain guide to the
minimum (0 - 0.5 mm).
Installation of the front derailleur
1. Adjust so that the clearance between the chain guide outer
plate and the large gear is 1 - 3 mm before installing.

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 forcarbon
frames.

If the chain falls to the crank side
Tighten the top adjustment screw clockwise
(about 1/4 turn).
If shifting is difficult from the small chainring to the
large chainring
Loosen the top adjustment screw
counterclockwise (about 1/8 turn).
If shifting is difficult from the large chainring to the
small chainring
Loosen the low adjustment screw
counterclockwise (about 1/8 turn).
If the chain falls to the bottom bracket side.
Tighten the low adjustment screw clockwise
(about 1/2 turn).
If the gear shifting to the small chainring is stiff and
difficult to carry out after trimming.
Turn the outer casing adjustment bolt
clockwise (1/8 of a turn at a time) until
shifting to the small chainring becomes
smooth. Be careful not to turn the outer
casing adjustment bolt too far at this time,
otherwise shifting to the large chainring will
become more difficult.
