General Safety Information
WARNING
“Maintenance interval depends on the usage and riding
circumstances. Clean regularly the chain with an appropriate
chaincleaner. Never use alkali based or acid based solvents
such as rust cleaners. If those solvent be used chain might
break and cause serious injury.”
• In order to obtain good gear shifting performance, this chain has a
forward side and a reverse side, and the sides are marked so that the
chain will face the correct way when installed. The proper design
performance will be obtained when the chain is installed so that it
faces the correct way. If it is installed so that it faces the opposite
way, the chain may come off and the bicycle may fall over and serious
injury may occur as a result.
• Use the reinforced connecting pin only for connecting the narrow type of chain.
•
If connecting pins other than reinforced connecting pins are used, or if a reinforced
connecting pin or tool which is not suitable for the type of chain is used, sufficient
connection force may not be obtained, which could cause the chain to break or fall off.
• Make sure that the connecting pin is aligned with the
outer link surface from the side that the pin is inserted. It
should feel smooth and flush when you run your finger
over it. The pin will protrude slightly on the backside after
the break off pin is removed.
• If it is necessary to adjust the length of the chain due to a
change in the number of sprocket teeth, make the cut at
some other place than the place where the chain has
been joined using a reinforced connecting pin. The chain
will be damaged if it is cut at a place where it has
been joined with a reinforced connecting pin.
• Check that the tension of the chain is correct and
that the chain is not damaged. If the tension is too
weak or the chain is damaged, the chain should be
replaced. If this is not done, the chain may break
and cause serious injury.
• 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.
• Read these Technical Service Instructions carefully, and keep them in a safe place
for later reference.
Note
• If gear shifting operations do not feel smooth, wash 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.
• You should periodically clean the derailleur and lubricate all moving parts
(mechanism and pulleys).
• If gear shifting adjustment cannot be carried out, check the degree of parallelism at
the rear end of the bicycle. Also check if the cable is lubricated and if the outer
casing is too long or too short.
• If you hear abnormal noise as a result of looseness in a pulley, you should replace
the pulley.
• You should periodically wash the sprockets in a neutral detergent and then
lubricate them again. In addition, cleaning the chain with neutral detergent and
lubricating it can be a effective way of extending the useful life of the sprockets and
the chain.
• If the chain keeps coming off the sprockets during use, replace the sprockets and
the chain.
• Use a frame with internal cable routing is strongly discouraged as it has tendencies
to impair the SIS shifting function due to its high cable resistance.
• Always be sure to use the sprocket set bearing the same
group marks. Never use in combination with a sprocket
bearing a different group mark.
• Use an outer casing which still has some length to spare even
when the handlebars are turned all the way to both sides.
Furthermore, check that the shifting lever does not touch the
bicycle frame when the handlebars are turned all the way.
• A special grease is used for the gear shifting cable. Do not
use DURA-ACE grease or other types of grease, otherwise
they may cause deterioration in gear shifting performance.
• Grease the inner cable and the inside of the outer casing before use to ensure that
they slide properly.
• For smooth operation, use the specified outer casing and the bottom bracket cable
guide.
• Operation of the levers related to gear shifting should be made only when the front
chainwheel is turning.
• The guide pulley has an arrow on it to indicate the direction of rotation. Install the
guide pulley so that the arrow is pointing counterclockwise when looking at the
outer side of the derailleur.
• The tension pulley has an arrow on it to indicate the direction of rotation. Install the
tension pulley so that the arrow is pointing clockwise when looking at the outer side
of the derailleur.
• 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.

The length of A will vary depending on the movement of the rear suspension.
Because of this, an excessive load may be placed on the drive system if the chain
length is too short. Set the length of the chain by adding two links to the chain when
the rear suspension is at a position where dimension "A" is longest and the chain is
on the largest sprocket and the largest chainring. If the amount of movement of the
rear suspension is large, the slack in the chain may not be taken up properly when
the chain is on the smallest chainring and smallest sprocket.
Adjustment
1. Top adjustment
Turn the top adjustment screw to adjust so
that the guide pulley is in line with the outer
line of the smallest sprocket when looking
from the rear.

3. Low adjustment
Turn the low adjustment screw so that the guide pulley moves to a position directly
in line with the largest sprocket.
4. How to use the B-tension adjustment screw
Mount the chain on the smallest chainring and the largest sprocket, and turn the
crank arm backward. Then turn the B-tension adjustment screw to adjust the
guide pulley as close to the sprocket as possible but not so close that it touches.
Next, set the chain to the smallest sprocket and repeat the above to make sure
that the pulley does not touch the sprocket.

Cutting the outer casing
When cutting the outer casing, cut the
opposite end to the end with the marking.
After cutting the outer casing, make the
end round so that the inside of the hole has a uniform diameter.
Attach the same outer
end cap to the cut end
of the outer casing.

The sealed cap with
tongue and the rubber
shield should be
installed to the outer
casing stopper of the
frame. Rubber shield

* If the rear derailleur moves to a large degree, such as in
bicycles with rear suspension, it is recommended that you
replace the cap with an aluminum
cap.
The end of the outer casing which
has the aluminum cap should be
at the derailleur side. Aluminum cap
Derailleur side
5. SIS Adjustment
Operate the shifting lever several times to move the chain to the
2nd sprocket. Then, while pressing the lever just enough to take
up the play in the lever, turn the crank arm.
When shifting to
3rd
Tighten the outer casing
adjustment barrel until the
chain returns to the 2nd
sprocket. (clockwise)
Loosen the outer casing
adjustment barrel until the
chain touches the 3rd sprocket
and makes noise. (counter
clockwise)
When no sound
at all is heard
Best setting
The best setting is when the shifting lever is
operated just enough to take up the play and the
chain touches the 3rd sprocket and makes noise.
* Return the lever to its original position (the position where
the lever is at the 2nd sprocket setting and it has been
released) and then turn the crank arm clockwise. If the
chain is touching the 3rd sprocket and making noise, turn the outer
casing adjustment barrel clockwise slightly to tighten it until the noise
stops and the chain runs smoothly.
Operate lever to change gears, and check that no noise occurs
in any of the gear positions.
For the best SIS performance, periodically lubricate all
power-transmission parts.
