General Safety Information
WARNING
"Maintenance interval depends on the usage and riding circumstances. Clean regularly the chain with an
appropriate chaincleaner. Never use alkali based or acid based solvents such as rust cleaners. If those
solvent be used chain might break and cause serious injury."
• 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
are used, or if a reinforced connecting pin or tool which
Chain
is not suitable for the type of chain is used, sufficient
9-speed super narrow chain
connection force may not be obtained, which could
such as
cause the chain to break or fall off.
CN-7701 / CN-HG93
8- / 7- / 6-speed narrow chain
such as
CN-HG50 / CN-HG40
• If it is necessary to adjust the length of the chain due to a change in the number of sprocket teeth, make the
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.
• It is important to periodically check the tightening torques for the crank arms and pedals. After riding approximately 100 km (60 miles), re-
check the tightening torques. If the tightening torques are too weak, the crank arms or pedals may come 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 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 the bicycle to fall
over and serious injury may occur as a result. We strongly recommend only using genuine Shimano replacement parts.
• 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.
CAUTION
• If the chain is on the smallest or intermediate chainring, there is the danger of injury from the tips of the teeth on the largest chainring.
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.
• When installing the pedals, apply a small amount of grease to the threads to prevent the pedals from sticking. Use a torque wrench to
securely tighten the pedals. Tightening torque: 35 - 55 N·m {305 - 479 in. lbs.}. The right-hand crank arm has a right-hand thread, and the left-
hand crank arm has a left-hand thread.
• 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 a effective way of extending the useful life of the chainrings and the chain.
• The cuffs of your clothing may get dirty from the chain while riding.
• 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.
• 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.
• 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.
