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 local bicycle dealer for their assistance.
•
Make sure to read all instruction 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.
•
All dealer’s manuals and instruction manuals can be viewed on-line on our website (http://si.shimano.com).
•
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.
DANGER
Failure to follow the instructions will result in death or serious injury.
WARNING
Failure to follow the instructions could result in death or serious injury.
CAUTION
Failure to follow the instructions could cause personal injury or physical damage to equipment and surroundings.

TO ENSURE SAFETY
WARNING
•
When installing components, be sure to follow the instructions that are given in the instruction manuals.
It is recommended that you use only genuine Shimano parts. If parts such as bolts and nuts become loose or damaged, the bicycle
may suddenly fall over, which may cause serious injury.
In addition, if adjustments are not carried out correctly, problems may occur, and the bicycle may suddenly fall over, which may
cause serious injury.
•
Be sure to wear safety glasses or goggles to protect your eyes while performing maintenance tasks such as replacing parts.
•
After reading the dealer’s manual thoroughly, keep it in a safe place for later reference.
Be sure to also inform users of the following:
•
Maintenance interval depends on the usage and riding circumstances. Clean regularly the chain with an
appropriate chain cleaner. Never use alkali based or acid based solvents such as rust cleaners. If those solvent be
used chain might break and cause serious injury.
•
Check the chain for any damage (deformation or crack), skipping, or other abnormalities such as unintended gear shifting. If
any problems are found, consult a dealer or an agency. The chain may break, and you may fall.
CAUTION
For Installation to the Bicycle, and Maintenance:
•
When installing and removing the plate and the plate unit, be careful to avoid injury such as getting your fingers caught by
the strong reaction force of the plate tension spring.
NOTE
Be sure to also inform users of the following:
•
When installing the SHADOW RD+, be sure to install the plate unit cover before riding the bicycle.
•
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.
•
Products are not guaranteed against natural wear and deterioration from normal use and aging.
•
For maximum performance we highly recommend Shimano lubricants and maintenance products.

For Installation to the Bicycle, and Maintenance:
•
Depending on the shape of the frame, the rear derailleur may interfere with the chain stay.
•
Because the high cable resistance of a frame with internal cable routing would impair the SIS function, this type of frame
should not be used.
•
Grease the inner cable and the inside of the outer casing before use to ensure that they slide properly.
•
Do not let dust adhere on the inner cable. If the grease on the inner cable is wiped off, the application of SIS SP41 grease
(Y04180000) is recommended. Do not use DURA-ACE grease or other types of grease, otherwise they may cause deterioration
in gear shifting performance.
•
For smooth operation, use the specified outer casing and the bottom bracket cable guide.
•
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.
•
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.
•
You should periodically clean the derailleur and lubricate all moving parts (mechanism and pulleys).
•
Depending on the model, the guide pulley has arrows on it to indicate the direction of rotation. Install the guide pulley so that
the arrows are 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.
•
If you hear abnormal noise as a result of looseness in a pulley, you should replace the pulley.
The actual product may differ from the illustration because this manual is intended chiefly to explain the procedures for using
the product.

ADJUSTMENT
This section describes the adjustment procedure for the SHADOW RD+.
Refer to ”Rear derailleur” in the General Operations for items not explained in this section.
How to use the end adjust bolt (SHADOW RD+)
Note:
Move the lever switch to the OFF position to reduce the tension of the plate tension spring before carrying out this
adjustment.
If the lever switch remains at the ON position so that the screw is difficult to turn, the screw may become damaged if you try to
force it to turn.
1.
Set the rear derailleur to the low gear.
2.
After stopping the wheel, check that the distance between the tip of the guide pulley and the tip of the gear is within the
range shown in the illustration.

Note:
If the number of teeth for the cassette sprocket is changed, carry out this setting again.
1.
Set the rear derailleur to the largest (at freeride mode) or the smallest (at downhill mode) gear position.
2.
Stop the wheel from turning, and then check that the distance from the edge of the guide pulley to the edge of the
sprocket is within the range as shown in the illustration.

If the frame interferes with the rear derailleur on models with a bump stopper when the plate unit is lifted up, turn the end
adjust bolt until there is no interference.
Load:
approx. 49 - 78.4 N
The frame and the rear derailleur should not interfere.
4.
Turn the crank arm to shift gears and check that there is no roughness in the feel.
