General Safety Information
In order to realize the best performance, we recommend that the following
combination be used.
Series
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.”
• 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.
• 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 - 14 N·m.
Furthermore, after riding approximately 100 km (60 miles), use a torque wrench to recheck 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,
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.
• If the inner cover is not installed correctly, the axle may rust and become damaged,
and the bicycle may fall over and serious injury may occur as a result.
• 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.

and the large gear is 1 - 3 mm before installing.

5. Check the operation of the indicator. If it does not operate
correctly, re-install the indicator by while taking particular
note of steps 3. and 4.
Do not disassemble the indicator and shifting lever unit, as this
may damage them or cause mis-operation.

Smooth shifting will not be possible if the chainrings are incorrectly installed, so be sure to install the
chainrings in the correct positions.

crank arm position.
With the marked surface of the smaller chainring
facing away from the crank arm, set the chainring
so that the o mark is lined up with the crank arm
position. For chainrings without a marked
surface, align using the projection on the inside
of the chainring.

• Install the shifting lever in a position where it will not obstruct brake
operation and gear shifting operation.
• Do not use in a combination which causes brake operation to be
obstructed.

(2) Adjustment of the inner cable tension
Turn the adjustment barrel of the shifting lever to adjust
the inner cable tension to the correct tension.
* If too much tension is applied to the cable, lever
operation may become stiff.

Replacement of the indicator
Disassembly and reassembly should only be carried out when
replacing the indicator.

Bottom bracket shell width (Thread dimensions)
• 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.
• Apply grease to the left and right adapters before installing them.
Outer casing holders
• For smooth operation, use the specified outer casing and the
bottom bracket cable guide.
• 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 DURAACE 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.
• Be sure to use only the applicable chain and bottom bracket.
• Make sure that the chainring combination matches the front chainwheel tooth
configuration in the Product specifications table. If other combinations are used, the
distance between the chainrings will be incorrect and the chain might slip off and get
caught in between them.
• If the bottom bracket shell is not parallel, gear shifting performance will drop.
• To ensure the best performance, be sure to use only the specified type of chain. The
wide type of chain cannot be used.
• 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.
While pulling the inner cable, tighten the wire fixing bolt with
a 5 mm allen key to secure the cable.
