General Safety Information
• 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.
• If the wheel becomes stiff and difficult to turn, you should lubricate it with grease.
• Do not apply any oil to the inside of the hub, otherwise the grease will come out.
• 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.
Group marks
• 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 (SIS-SP41). 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.
• If the brake fluid used in the oil disc brakes is of a type which tends to adhere to the plastic parts of the shifting lever, this may
cause the plastic parts to crack or become discolored. Therefore, you should make sure that the brake fluid does not adhere to
these plastic parts.
The mineral oil which is used in SHIMANO disc brakes does not cause cracking or discoloration if it adheres to plastic parts, but
such parts should be cleaned with alcohol beforehand to prevent foreign particles from adhering.
• Do not disassemble the indicator and shifting lever unit, as this may damage them or cause mis-operation.
• Be sure to read these service instructions in conjunction with the service instructions for the RD-M592 before use.
• 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.

for their recommendation on tightening torque in order to prevent
over tightening that can cause damage to the carbon material

the components.

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.
Do not disassemble the indicator and shifting lever unit, as this may
damage them or cause mis-operation.

When cutting the outer casing, cut the opposite end to the end

Installation of the lever
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.

the lever is at the 2nd sprocket setting and it has been

stops and the chain runs smoothly.

• Check that the wheels are fastened securely before riding the bicycle. If the wheels are loose in any way, they may come off the
bicycle and serious injury may result.
• 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.

• 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.

• Use a front chainwheel which is compatible with 9-speed chains in conjunction with Shimano
CN-7701, CN-HG93 and CN-HG73 chains. If a chainwheel for an 8-speed chain or less is used, front chainwheel gear shifting
problems may occur, or the chain pins might fall out, causing the chain to break.
• 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
• 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.
