Please note: specifications are subject to change for improvement without notice. (English) © Apr. 2009 by Shimano Inc. XBC SZK Printed in Japan.
This service instruction explains how to useand maintain the Shimano bicycle partswhich have been used on your new bicycle.For any questions regarding your bicycle orother matters which are not related toShimano parts, please contact the place ofpurchase or the bicycle manufacturer.
General Safety Information
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 pinsare used, or if a reinforced connecting pin or tool whichis not suitable for the type of chain is used, sufficientconnection force may not be obtained, which couldcause the chain to break or fall off.
• If it is necessary to adjust the length of the chain dueto a change in the number of sprocket teeth, make thecut at some other place than the place where the chainhas been joined using a reinforced connecting pin or an end pin. The chain will be damaged if itis cut at a place where it has been joined with a reinforced connecting pin or an end pin.
• Be careful not to let the cuffs of your clothes get caught in the chain while riding, otherwise youmay fall off the bicycle.
• Check that the tension of the chain is correct and that the chain is not damaged. If the tensionis too weak or the chain is damaged, the chain should be replaced. If this is not done, the chainmay 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 problemsmay occur, or the chain pins might fall out, causing the chain to break.
• The two left crank arm mounting bolts should be tightened alternately in stages rather than each bolt being fully tightened all atonce. Use a torque wrench to check that the final tightening torques are within the range of 12 - 14 N·m.Furthermore, after riding approximately 100 km (60 miles), use a torque wrench to re-check the tightening torques.It is also important to periodically check the tightening torques.If the tightening torques are too weak or if the mounting bolts are not tightened alternately in stages, the left crank arm maycome off and the bicycle may fall over, and serious injury may occur as a result.
• Check that there are no cracks in the crank arms before riding the bicycle. If there are any cracks, the crank arm may break andyou may fall off the bicycle.
• If the inner cover is not installed correctly, the axle may rust and become damaged, and the bicycle may fall over and seriousinjury may occur as a result.
• Obtain and read the service instructions carefully prior to installing the parts. Loose, worn or damaged parts may cause thebicycle to fall over and serious injury may occur as a result. We strongly recommend only using genuine Shimano replacementparts.
• Obtain and read the service instructions carefully prior to installing the parts. If adjustments are not carried out correctly, thechain 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.

Note• In addition, if pedaling performance does not feel normal, check this once more.• Before riding the bicycle, check that there is no play or looseness in the connection. Also, be sure to retighten the crank arms
and pedals at periodic intervals.• If a squeaking noise is heard coming from the bottom bracket axle and the left crank arm connector, apply grease to the connector and
then tighten it to the specified torque.• Do not wash the bottom bracket with high-pressure jets of water.• If you feel any looseness in the bearings, the bottom bracket should be replaced.• 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 wash the chainrings in a neutral detergent and then lubricate them again. In addition, cleaning the chain
with neutral detergent and lubricating it can be an effective way of extending the useful life of the chainrings and the chain.• If the chain keeps coming off the chainrings during use, replace the chainrings and the
chain.• When the chain is in the position shown in the illustration, the chain may contact the front
chainrings or front derailleur and generate noise. If the noise is a problem, shift the chainonto the next-larger rear sprocket or the one after.
• Apply grease to the left and right adapters before installing them.• For smooth operation, use the specified outer casing and the bottom bracket cable guide.• This front derailleur is for triple front chainwheel use only. It cannot be used with the
double front chainwheel, as the shifting points do not match.• When installing the top route type, choose a frame that has three outer casing holders as shown in the
illustration at right.• 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 thehandlebars are turned all the way.
• A special grease is used for the gear shifting cable (SIS-SP41). Do not use DURA-ACE grease or othertypes 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.• 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 tothese plastic parts.The mineral oil which is used in SHIMANO disc brakes does not cause cracking or discoloration if it adheres to plastic parts, butsuch 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.• 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.

! NoteWhen installing the components to carbon frame/handle barsurfaces, verify with the manufacturer of the carbon frame/parts fortheir recommendation on tightening torque in order to prevent overtightening that can cause damage to the carbon material and/orunder tightening that can cause lack of fixing strength for thecomponents.
Attach the same outer end cap to the cut end of the outer casing.

Disassembly and reassembly should only be carried out whenremoving or replacing the indicator. For the front, the direction ofrotation when removing and installing is opposite to the position ofthe needle.
Chain length on bicycles with rear suspension
The length of A will vary depending on the movement of the rearsuspension. Because of this, an excessive load may be placed onthe drive system if the chain length is too short. Set the length ofthe chain by adding two links to the chain when the rear suspensionis at a position where dimension "A" is longest and the chain is onthe largest sprocket and the largest chainring. If the amount ofmovement of the rear suspension is large, the slack in the chainmay not be taken up properly when the chain is on the smallestchainring and smallest sprocket.

If not using the indicator, this shifting lever can be installed eitheron the inside or the outside of the brake lever.If adjusting the position, remove the indicator, and then be sureto secure it in the new position with the two fixing bolts.
• Install the shifting lever in a position where it will not obstruct brakeoperation and gear shifting operation.
• Do not use in a combination which causes brake operation to beobstructed.
• When installing the components to carbon frame/handle barsurfaces, verify with the manufacturer of the carbon frame/parts fortheir recommendation on tightening torque in order to prevent overtightening that can cause damage to the carbon material and/orunder tightening that can cause lack of fixing strength for thecomponents.
Installation of the lever
Use a handlebar grip with a maximumouter diameter of 36 mm.

General Safety Information
WARNING
Note• 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.• 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 thehandlebars are turned all the way.
• A special grease is used for the gear shifting cable (SIS-SP41). Do not use DURA-ACE grease or othertypes 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 tothese plastic parts.The mineral oil which is used in SHIMANO disc brakes does not cause cracking or discoloration if it adheres to plastic parts, butsuch 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.• 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.
• Check that the wheels are fastened securely before riding the bicycle. If the wheels are loose in any way, they may come off thebicycle 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 resultin 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 connectingpins are used, or if a reinforced connecting pin or toolwhich is not suitable for the type of chain is used,sufficient connection force may not be obtained, whichcould cause the chain to break or fall off.
• If it is necessary to adjust the length of the chain dueto a change in the number of sprocket teeth, make thecut at some other place than the place where the chainhas been joined using a reinforced connecting pin or an end pin. The chain will be damaged if itis 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 tensionis too weak or the chain is damaged, the chain should be replaced. If this is not done, the chainmay break and cause serious injury.
• Use a front chainwheel which is compatible with 9-speed chains in conjunction with ShimanoCN-7701, CN-HG93 and CN-HG73 chains. If a chainwheel for an 8-speed chain or less is used, front chainwheel gear shiftingproblems 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 thebicycle to fall over and serious injury may occur as a result. We strongly recommend only using genuine Shimano replacementparts.
• Obtain and read the service instructions carefully prior to installing the parts. If adjustments are not carried out correctly, thechain 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.
