Notes:

• 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.

• For smooth operation, use the specified outer casing and

the bottom bracket cable guide.

• For maximum performance we highly recommend Shimano

lubricants and maintenance products.

• To ensure the best performance, be sure to use only the

specified type of chain. The wide type chain cannot be

used.

50 - 70 Nm

{435 - 608 in. lbs.}

Install using the special tool TL-UN73.

First install the main body, then the adapter.

Tightening torque:

35 - 50 Nm

{305 - 435 in. lbs.}

Installation of the front chainwheel

1. Use the cotterless crank

extractor (TL-FC10) to install

the front chainwheel.

Installation of the front derailleur

1. Install so that there is 1 -3 mm of clearance at the closest

point between

the largest

chainring and

the bottom edge

of the chain

guide.

2. The level section of the chain guide outer plate should

be directly above and parallel to the largest chainring.

3. Secure using a 9mm spanner.

2. Connection and securing of cable

Connect the cable to the rear derailleur and, after taking up the initial

slack in the cable, reattach to the rear derailleur as shown in the

illustration.

Secure the cable by pulling it with pliers with a force of 5-10 kg.

Tightening torque:

5 - 7 Nm {44 - 60 in. lbs.}

NOTE:

To mount the shifting

lever in a top-mount

position, install it so

that it cannot touch the

brake lever.

Do not allow them to touch each other.

• 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.

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.

• 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.
