SERVICE INSTRUCTIONS
SI-R710C
Rear 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 connecting pin or
an end pin.

• 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.

* 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.
* Because the high cable resistance of a frame with
internal cable routing would impair the SIS function,
this type of frame should not be used.
* 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.
* 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.
In order to realize the best performance, we recommend that the following combination be used.

Installation of the sprockets
• For installation of the sprockets,
use the special tool (TL-HG16) to
tighten the lock ring.
For each sprocket, the
surface that has the
group mark should face
outward and be
positioned so that the
triangle (U) mark on
each sprocket and the A
part (where the groove
width is wide) of the
freewheel body are
aligned.

to the chain connecting pin to check that
the inner link width is correct.
Check that the connecting pin pro-trudes
past the outer link by the same amount on
both sides, and that the amount of
protrusion is 0.2 mm or more.

Replacement of the freewheel body
After removing the hub axle,
remove the freewheel body
fixing bolt (inside the freewheel
body), and then replace the
freewheel body.
Note:
Do not attempt to disassemble
the freewheel body, because it
may result in a malfunction.

Remove the two indicator fixing screws which are
securing the indicator, and then remove the indicator unit
as shown in the illustration.
Operate lever (B) 8 or more times to set the lever to the
highest position. Pass the inner cable through the lever
hole and hook it onto the lever, and then secure the
indicator unit with the two indicator fixing screws.

Tightening torque:
5 - 7 Nm {44 - 60 in. lbs.}
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.
3. Low adjustment
Turn the low adjustment screw
so that the guide pulley moves
to a position directly in line with
the largest sprocket.

4. How to use the B-tension
adjustment screw
Mount the chain on the smallest
chainring and the largest sprocket, and
turn the crank arm
backward. Then turn the
B-tension adjustment screw to adjust
the guide pulley as close to the
sprocket as possible but not so close
that it touches. Next, set the chain to
the smallest sprocket and repeat the
above to make sure that the pulley
does not touch the sprocket.

5. SIS Adjustment
(1) Operate the shifting lever to move the
3rd 2nd Top
chain from the top gear to the 2nd gear.
* If the chain will not move to the 2nd
gear, turn the outer casing adjustment
barrel to increase the tension ----- ➀
(counter clockwise)
* If the chain moves past the 2nd gear,
decrease the tension --- ➁ (clockwise)

(2) Next with the chain on the 2nd
gear, increase the inner cable
tension ➀ while turning the
crank arm forward. Stop turning
the outer casing adjustment
barrel just before the chain
makes noise against the 3rd
gear.
This completes the adjustment.
