General Safety Information
Adjust and then install the front derailleur as shown in the illustration. Do not remove the Pro-Set alignment block at this time.
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.

Install the inner hole cover by turning it as shown in the illustration until it stops. Do not turn it any further than this, otherwise it may damage the screw thread.
Note • 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 Front noise. If the noise is a problem, shift the chain onto the next-larger chainrings rear sprocket or the one after. • Shimano does not provide the bottom bracket mount fixing bolts. Rear • For smooth operation, use the specified outer casing and the bottom sprockets 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.
After taking up the initial slack in the cable, re-secure to the front derailleur as shown in the illustration.

Set so that the clearance between the chain guide outer 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.
