Rear Drive System

General Safety Information

WARNING

• 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. If connecting pins other than

reinforced connecting pins are used, or if a reinforced connecting pin or tool which is

not suitable for the type of chain is used, sufficient connection force may not be

obtained, which could cause the chain to break or fall off.

Chain

9-speed super narrow chain

such as

CN-7701 / CN-HG93

8- / 7- / 6-speed narrow

chain such as

CN-HG50 / CN-IG51

• 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.

• 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.

• 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

• 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.

• 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 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.

• 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.
