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 pins
Chain
are used, or if a reinforced connecting pin or tool which
is not suitable for the type of chain is used, sufficient
9-speed super narrow
connection force may not be obtained, which could
chain such as
cause the chain to break or fall off. CN-7701 / CN-HG93
• If it is necessary to adjust the length of the chain due 8- / 7- / 6-speed narrow
chain such as
to a change in the number of sprocket teeth, make the
CN-HG50 / CN-IG51
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.
• Be careful not to let the cuffs of your clothes get caught in the chain while riding, otherwise you
may fall off the bicycle.
• 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.
• The two left crank arm mounting bolts should be tightened alternately in stages rather than each bolt being fully tightened all at
once. Use a torque wrench to check that the final tightening torques are within the range of 12 - 15 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 may
come off and the bicycle may fall over.
• Check that there are no cracks in the crank arms before riding the bicycle. If there are any cracks, the crank arm may break and
you may fall off the bicycle.
• 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
• In addition, if pedaling performance does not feel normal, check this once more.
• Check that there is no looseness in any joints or connections before riding the bicycle. (BB-FC, FC-PD)
• Do not wash the bottom bracket with high-pressure jets of water.
• If you feel any looseness in the bottom bracket axle, 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 chain
onto the next-larger rear sprocket or the one after.
• Apply grease to the bottom bracket before installing it.
• 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 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.
• 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.
• 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.

Gear shifting operation
Both lever (A) and lever (B) always return to the initial position when they are released after shifting.
When operating one of the levers, always be sure to turn the crank arm at the same time.
To shift from a small chainring to a larger chainring
When lever (A) is pressed once, there is a shift of one step
from a small chainring to a larger chainring.
