General Safety Information

WARNING

• 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

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

guide.

• Grease the inner cable and the inside of the outer casing before use to ensure that

they slide properly.

• 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.

• Operation of the levers related to gear shifting should be made only when the front

chainwheel is turning.

• 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. Do not use DURA-ACE grease

or other types of grease, otherwise they may cause deterioration in gear shifting

performance.

• Do not disassemble the indicator and shifting lever unit, as this may damage them

or cause mis-operation.

• 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.

Shifting lever

When lever (B) is operated, there is one click where trimming

(the noise prevention mechanism) engages, and a second

stronger click when the gear shift stroke is completed. After

trimming, the next push will complete the gear shift stroke.

To shift from a large chainring to a smaller chainring

(Lever B)

When lever (B) is pressed once,

there is a shift of one step from

a large chainring to a smaller

chainring.

Example:

from largest chainring to

intermediate chainring.

This release lever is equipped with a 2-way release mechanism which allows release operations to be carried out by either pushing or pulling

the lever. Both lever (A) and lever (B) always return to the initial position when they are released after shifting. When operating one of the

levers, always be sure to turn the crank arm at the same time.

Gear shifting operation

Trimming (noise prevention operation)

If the chain is on the large front chainwheel and the larger rear

sprocket, the chain will rub in the front derailleur plate,

producing a characteristic noise. When this happens, press

lever (B) lightly (to the point where it clicks); this causes the

front derailleur to move slightly

towards the smaller chainwheel,

thereby eliminating the noise.

front derailleur

Chain position

Mounting the shifting lever

Use a handlebar grip with a maximum outer diameter of 32 mm (SL-R780) /

36 mm (SL-4600).

< Front > < Rear >

1. Loosen the cable fixing bolt (nut) of the front derailleur or rear derailleur, and then pull the inner cable out of

the shifting lever unit in the same way as when installing the inner cable.

2. Remove the indicator unit by following the disassembly procedure given in “Replacement and assembly of

the indicator unit”.

3. Remove the four shifting lever unit mounting screws, and then remove the shifting lever unit as shown in the

illustration.

4. Align the shifting lever unit and the bracket, and then secure with the four shifting lever unit mounting

screws.

5. Install the indicator unit by following the assembly procedure given in “Replacement and assembly of the

indicator unit”.

Disassembly and reassembly should only be carried out when

replacing the shifting lever unit.

Disassembly and reassembly should only be carried out when the

indicator unit is being replaced.

< Disassembly >

1. Remove the two indicator fixing screws.

2. Turn the indicator unit in the clockwise direction as shown in the

illustration, and then lift it up to remove it.

(For the front: Turn it counterclockwise.)

< Assembly >

1. Operate lever B 9 times or more to set it to the highest position.

(For the front: Operate lever B 2 times or more to set it to the lowest position.)

2. Check that the indicator needle is at the left edge.

(For the front: Check that the needle is at the right edge.)

3. Insert the pin at the bottom of the indicator into the hole in the winder unit and

then insert the indicator unit so that the two bosses are aligned with the

marks on the shifting lever unit.

4. Turn the indicator unit counterclockwise as shown in the illustration to install it.

(For the front: Turn it clockwise.)

5. Secure the indicator unit by tightening the two indicator fixing screws.

6. Check the operation. If the indicator unit does not operate correctly,

reassemble while paying particular attention to steps 1, 2 and 3.

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.

Note:

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 components.

• 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.

Installing the inner cable

1. Operate lever B 9 times or more to set it to the highest position.

(For the front: Operate lever B 2 times or more to set it to the lowest

position.)

2. Check that the indicator needle is at the left edge.

(For the front: Check that the needle is at the right edge.)

3. Remove the inner hole cover and install the cable.

The levers are equipped with a multi release function which lets you

shift two gears with a single release operation. (SL-R780 only)

To shift from a small sprocket to a larger sprocket

(Lever A)

You can vary the lever stroke to shift the desired number of gears,

so that to shift by one gear only, move the lever to the (1) position,

and to shift by two gears at one time, move the lever to the (2)

position. A maximum two-gear shift can be made in this manner.

To shift from a large sprocket to a smaller sprocket

(Lever B)

< SL-R780 >
