returns to the 2nd sprocket.
(clockwise)
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.

WARNING
In order to realize the best performance, we
recommend that the following combination be used.
Installation of the rear derailleur
Specifications
Chain length
Cable securing and stroke adjustment
1. Top adjustment
Turn the top adjustment screw to adjust so that the guide pulley is
below the outer line of the smallest sprocket when looking from the
rear.
2. Connection and securing of cable
Connect the cable to the rear derailleur and, after taking up the
initial slack in the cable, reattach to the rear derailleur as shown in
the illustration.
Secure the cable by pulling it with pliers with a
force of 5 - 10 kg.
3. Low adjustment
Turn the low adjustment screw so that the guide pulley moves to a
position directly below the largest sprocket.
Place the outer casing so that it does not touch the basket and
mudguard, otherwise it may cause a problem with the performance of
the derailleur.

• If routing the casing upward:
Add 10 mm to the length of the outer casing
from the end that is inserted into the outer
casing holder to the end which is inserted into
the link.

• 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
• The reinforced connecting pins cannot be used with the UG chain,
otherwise the connections will not move properly and noise will
occur.
• 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.
• 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.

Operate the shifting lever several times to move

pressing the lever just enough to take up the
play in the lever, turn the crank arm.
For the best SIS performance, periodically lubricate all power-
transmission parts.
