IMPORTANT NOTICE
IMPORTANT NOTICE
••This dealer's manual is intended primarily for use by professional bicycle mechanics.
Users who are not professionally trained for bicycle assembly should not attempt to
install the components themselves using the dealer's manuals.
If any part of the information on the manual is unclear to you, do not proceed with the
installation. Instead, contact your place of purchase or a distributor for assistance.
••Make sure to read all manuals included with the product.
••Do not disassemble or modify the product other than as stated in the information
contained in this dealer's manual.
••For consumers who do not have easy access to the internet, please contact a SHIMANO
distributor or any of the SHIMANO offices to obtain a hardcopy of the User's Manual.
••Please observe the appropriate rules and regulations of the country, state or region in
which you conduct your business as a dealer.
For safety, be sure to read this dealer's manual thoroughly before use, and
follow it for correct use.
The following instructions must be observed at all times in order to prevent personal injury
and physical damage to equipment and surroundings.
The instructions are classified according to the degree of danger or damage which may occur
if the product is used incorrectly.

TO ENSURE SAFETY
TO ENSURE SAFETY
WARNING
••Be sure to follow the instructions provided in the manuals when installing the product.
Only use SHIMANO genuine parts. If a component or replacement part is incorrectly
assembled or adjusted, it can lead to component failure and cause the rider to lose
control and crash.
•• Wear approved eye protection while performing maintenance tasks such as
replacing components.
••Check the chain for any damage (deformation or cracking), skipping, or other
abnormalities such as unintended gear shifting. If any problems are found, consult your
place of purchase or a distributor. The chain may break, and you may fall.
CAUTION
NOTICE
Be sure to also inform users of the following:
••For SHADOW RD+, be sure to check that the plate unit cover and the plate unit rubber
cap are installed before riding the bicycle.
••If gear shifting operation does not feel smooth, consult the place of purchase for
assistance.
••The gears should be periodically washed with a neutral detergent then lubricated. In
addition, cleaning the chain and QUICK-LINK with a neutral detergent and lubricating
them can be an effective way of extending the life of the chain and QUICK-LINK.
••Products are not guaranteed against natural wear and deterioration from normal use
and aging.
5
TO ENSURE SAFETY
••Grease with SIS SP41 grease (Y04180000) the inner cable and the sliding portions of the
outer casing before use to ensure that they slide properly. Do not let dust adhere to the
inner cable.
••Use an OT-SP41 outer casing and a cable guide for smooth operation.
••Use an outer casing which still has some length to spare even when the handlebars are
turned all the way to either side. Furthermore, check that the shifting lever does not
touch the bicycle frame when the handlebars are turned all the way.
••If gear shifting adjustments cannot be carried out, check the alignment of the dropout
and check if the cable is lubricated or if the outer casing is too long or too short.
••Periodically clean the shifting unit and lubricate all moving parts (mechanism and
pulleys).
••Note the installation direction of the pulleys. Depending on the model, the pulley has
arrows on it to indicate the direction of rotation. Install the pulley so that the arrows are
pointing counterclockwise when looking at the outer side of the shifting unit.
••If you hear abnormal noise as a result of excess play in a pulley, you should replace the
pulley.
The actual product may differ from the illustration because this manual is
intended mainly to explain the procedures for using the product.

NOTICE
••The rear derailleur plate assembly is equipped with a pin or plate that prevents
chain derailment. When passing the chain through the rear derailleur, pass it
through the main body of the rear derailleur from the side of the chain
derailment prevention plate as shown in the figure.
••If the chain is not passed through the correct position, damage may be caused to
the chain or the rear derailleur.

••For full suspension bikes, length [a] will vary according to the movement of the
rear suspension.
After shifting to the largest chainring and the largest sprocket, make sure that the
chain length is not too short when dimension [a] is at its maximum extension.
If the chain length is too short, drivetrain components may be damaged due to
excessive load on the drivetrain.

TECH TIPS
••If the motion of the rear derailleur is extreme, such as in bicycles with a rear
suspension, replacing the sealed outer cap with the supplied aluminum type
sealed outer cap is recommended.
3. Cut off any excess outer casing with the cable cutter.
After cutting, return the outside of the outer casing to a perfect circle so that the inside
of the hole has a uniform shape.
4. Install the sealed outer cap to the end of the outer casing.
Route the inner cable through the outer casing.

5. Install the sealed outer cap with tongue and rubber shield onto the
outer casing stopper of the frame.
For bikes with full length outer casing, this step is not necessary.
Be careful not to bend the tongue.
CAUTION
••Do not allow the wheel to turn while securing the inner cable and installing the inner
end cap. Otherwise, you may touch the wheel and be injured.

••For RD-M9100/RD-M9120, replacing the cover with tongue is recommended
when replacing the inner cable.
••Cables with a polymer coating may develop a fuzzy appearance or texture
