General Safety Information
WARNING
•• Install a bashguard (165 mm) to the front chainwheel. If the bashguard is
not installed, the chain may come off the chainrings or damage to the
chainrings may occur. If the bashguard used is larger than 165 mm, it
may interfere with the front derailleur and problems with shifting may
occur.
•• Be careful not to let the cuffs of your clothes get caught in the chain
while riding, otherwise 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.
Note
•• Turn the top adjustment screw to adjust so that the chain does not sit on
top of the bash guard.
•• 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.
•• 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.

•• For smooth operation, use the specified outer casing and the bottom
bracket cable guide.
•• 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.

Installation of the front derailleur
Adjust and then install the front derailleur as shown in the
illustration. Do not remove the Pro-Set alignment block at this time.
<Front derailleur height and parallelism adjustment>
With the flat part of the chain guide outer plate on the inside of the
bash guard as shown in the illustration, adjust the height of the front
derailleur so that the outer edge of the bash guard is within the
specified range on the Pro-Set gauge. Also adjust so that the flat
part of the outer plate is parallel to the inner surface of the bash
guard. Use a 5 mm Allen key to tighten.

When installing the components to carbon frame/handle bar
surfaces, verify with the manufacturer of the carbon frame/parts for
their recommendation on tightening torque in order to prevent over
tightening that can cause damage to the carbon material and/or
under tightening that can cause lack of fixing strength for the
SI-5KY0A-002
components.

2. Connecting and securing the inner cable
Operate lever (B) two times or more,
and check on the indicator that the
lever is at the lowest position. Then
remove the inner hole cover and
connect the inner cable.
Install the inner hole cover by turning it as
shown in the illustration until it stops.

Cutting the outer casing
After cutting the outer casing, make the
end round so that the inside of the hole
has a uniform diameter.
