SERVICE INSTRUCTIONS
SI-F915B
Front Drive System
Before use, read these instructions carefully, and follow them for correct use.
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 pin 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.

• 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

• Obtain, read and carefully service instructions when installing parts. A loose, worn, or
damaged parts may cause injury to the rider.
We strongly recommend that only genuine Shimano replacement parts be used.
Note
• Apply grease to the bottom bracket before installing it.
• For smooth operation, use the specified outer casing and bottom bracket cable guide.
• This front derailleur is for triple front chainwheel use only. It cannot be used
Outer casing holders
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.
• 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.

2. Securing the inner cable
Inserting the inner cable
Insert the inner cable into the outer casing from the end
with the marking on it. Apply grease from the end with the
marking in order to
maintain cable
operating efficiency.
Marking
Cutting the outer casing
When cutting the outer casing, cut the opposite end to the
end with the marking. After cutting the
outer casing, make the end round so
that the inside of the hole has a
uniform diameter.
Attach the same outer end cap to the cut end of the outer
casing.

Cut off the excess length of inner cable
and then install the inner end cap.
Note:
Pass the cable
through as shown
in the illustration.

5. Troubleshooting chart
After completion of steps 1 - 4, move the shifting lever to check the
shifting. (This also applies if shifting becomes difficult during use.)
If the chain falls to the crank side.
Tighten the top adjustment
screw clockwise (about 1/4 turn).
If shifting is difficult from the
intermediate chainring to the largest
chainring.
Loosen the top adjustment
screw counterclockwise
(about 1/8 turn).
If shifting is difficult from the
intermediate chainring to the smallest
chainring.
Loosen the low adjustment
screw counterclockwise
(about 1/4 turn).
If there is interference between the
chain and the front derailleur inner
plate at the largest chainring.
Tighten the top adjustment
screw clockwise (about 1/8 turn).
If there is interference between the
chain and the front derailleur outer
plate at the largest chainring.
Loosen the top adjustment
screw counterclockwise
(about 1/8 turn).
If the intermediate chainring is skipped
when shifting from the largest
chainring.
Loosen the outer casing
adjustment barrel
counterclockwise (1 or 2 turns).
If there is interference between the
chain and front derailleur inner plate
when the rear sprocket is shifted to
the largest sprocket when the
chainwheel is at the intermediate
chainring position.
Tighten the outer casing
adjustment barrel clockwise
(1 or 2 turns).
If the chain falls to the bottom bracket
side.
Tighten the low adjustment
screw clockwise (about 1/2 turn).
Installing the CI-Deck
1. Install to a handlebar with a diameter of 25 mm. (Use an
adapter if the handlebar diameter is 22 mm.)
2. The CI-Deck can be
adjusted within a range of
30 degrees. Loosen the
bolt of the clamp band to
adjust.
Turn the pulley and remove the cable as shown in the illustration.
Turn the pulley clockwise, and then insert the end of the new
cable until it is in the position shown in the illustration.
Install the indicator, lens cover and cover in that order.

3. The length of the cable which connects the CI-Deck and
the Revoshift unit will vary depending on the handlebars
being used. If the cable is too long or too short, the
indicator display will not be correct.
4. Replacement of the indicator cable
< At the CI-Deck side >
Remove the cover fixing screws and then remove the
cover, lens cover and indicator as shown in the
illustration.

Turn the adjustment bolt to remove it,
and then remove the cable from the
Revoshift lever main unit.
Pull the end of the new cable until it is
positioned in the pulley as shown in the
illustration.
Check that the cable is securely in the
groove at this time.
Tighten the adjustment bolt,
install the cover and secure
it with the screws.
