Installation of the rear derailleur

When installing, be careful that deformation is not caused by the
B-tension adjustment screw coming into contact with the dropout tab.

2. Connection and securing of
the cable

Connect the cable to the rear
derailleur and, after taking up the
initial slack in the cable,
re-secure to the rear derailleur as
shown in the illustration.

5 - 7 N·m {44 - 60 in. lbs.}

Note:

Be sure that the
cable is securely
in the groove.

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.

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.

touches the 3rd
sprocket and makes
noise. (counter

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.

General Safety Information

Chain toolChain

WARNING

• Use neutral detergent to clean the chain. Do not use alkali-based or
acid based detergent such as rust cleaners as it may result in
damage and/or failure of the chain.

• Use the reinforced connecting pin only for connecting the narrow
type of chain.

• There are two different types of reinforced connecting pins available.
Be sure to check the table below before selecting which pin to use. 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.

• 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 or an end pin. The chain will be
damaged if it is cut at a place where
it has been joined with a reinforced
connecting pin or an end 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 injury to the
rider.
We strongly recommend only using genuine Shimano replacement
parts.

• Read these Technical Service Instructions carefully, and keep them
in a safe place for later reference.

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.

• 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.

• 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.

• 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.

• 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.
