General Safety Information
WARNING
• Be careful not to let the cuffs of your clothes get caught in the chain while riding, otherwise you may fall off
the bicycle.
• 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
• 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.
• If gear shifting operations do not feel smooth, wash 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.
• For frames with suspension, the chain stay angle will vary depending
on whether the bicycle is being ridden or not being ridden. When the
bicycle is not being ridden and the chain is positioned on the
largest/larger chainring and on the smallest sprocket, the chain guide outer plate of the front derailleur may
touch the chain.
• Shimano does not provide the bottom bracket mount fixing bolts.
• For smooth operation, use the specified outer casing and the bottom bracket cable guide.
• 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.
• Be sure to read the service instructions for the Front Drive System in conjunction with these service
instructions.

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.
• FD-M980 / M981
Install the front derailleur as shown in the
illustration. At this time, adjust the position of
the front derailleur while installing it so that
there is a clearance of 1 - 3 mm between the
chain guide outer plate and the maximum outer
diameter of the larger chainring.
