when installing parts. A loose, worn, or damaged
parts may cause injury to the rider.
We strongly recommend that only genuine Shimano

• If gear shifting operations cannot be carried out
smoothly, clean the derailleur and lubricate all
moving parts.
• If the amount of looseness in the links is so great
that adjustment is not possible, you should replace
the derailleur.
• When the chain is in the position shown in the
illustration, the chain may contact the front
chainrings or front derailleur and generate noise.
If the noise is a problem, shift the chain onto the
next-larger rear sprocket or the one after.

• If attaching the FD-2203 (brazed-on type) to a seat
tube with a thickness of more than 31.8 mm, the
derailleur may come into contact with the seat tube
and interfere with normal gear shifting performance.
• For smooth operation, always be sure to use the
specified outer casing and the bottom bracket cable
guide.
• Grease the inner cable and the inside of the outer
casing before use to ensure that they slide properly.
• This front derailleur is for triple front chainwheel use
only. It cannot be used with the double front
chainwheel, as the shifting points do not match.
• For the chain, be sure to use only the Shimano
narrow type chain. The wide type chain cannot be
used.
• 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.

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).
