2. The level section of the chain guide outer plate should be directly above and parallel
to the largest chainring.
3. Secure using a 9 mm spanner (TY10, TZ31, TZ30) or a 5 mm Allen key (TX51,
TX50).
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.
4. Top adjustment
Set so that the clearance between the
chain guide outer plate and the chain
is 0 - 0.5 mm.
Add 2 links (with the chain on both the largest
sprocket and the largest chainring)
Be sure to follow the sequence described below.
1. Low adjustment
First remove the Pro-Set alignment block.
Next, set so that the clearance between
the chain guide inner plate and the chain
is 0 - 0.5 mm.

2. Connection and securing of cable
While firmly pulling the cable, tighten the fixing bolt with a 9 mm spanner
(TY10, TZ31, TZ30) to secure the cable.
3. Adjustment of cable tension
After taking up the initial slack in the cable, re-secure to the front derailleur as
shown in the illustration.

5. Adjustment of the intermediate chainring
Set the chain onto the largest sprocket, and at the front, move the chain from
the largest chainring to the intermediate chainring. Adjust using the cable
adjusting bolt so that the clearance between the chain guide inner plate and
the chain is 0 - 0.5 mm.

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.
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.
Attach the same outer end cap to the
cut end of the outer casing.

Replacing the inner cable
1. Operate the shifter to set it to the low
position. Loosen the screws at point A and B
with a screw driver in order to remove the
cover.
2. Replace the inner cable by carrying out steps
1 to 3 as shown in the illustrations.
If the chain falls to the crank side.
If shifting is difficult from the
intermediate chainring to the largest
chainring.
If shifting is difficult from the
intermediate chainring to the
smallest chainring.
If there is interference between the
chain and the front derailleur inner
plate at the largest chainring.
If there is interference between the
chain and the front derailleur outer
plate at the largest chainring.
If the intermediate chainring is
skipped when shifting from the
largest chainring.
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.
If shifting is difficult from the largest
chainring to the intermediate
chainring.
If the chain falls to the bottom
bracket side.
Tighten the top adjustment screw
clockwise (about 1/4 turn).
Loosen the top adjustment screw
counterclockwise (about 1/8 turn).
Loosen the low adjustment screw
counterclockwise (about 1/4 turn).
Tighten the top adjustment screw
clockwise (about 1/8 turn).
Loosen the top adjustment screw
counterclockwise (about 1/8 turn).
Loosen the outer casing adjustment
barrel counterclockwise (1 or 2 turns).
Tighten the outer casing adjustment
barrel clockwise (1 or 2 turns).
Tighten the low adjustment screw
clockwise (about 1/2 turn).
