SI-5LX0B-001-00 General Safety Information In order to realize the best performance, we recommend that the following combination be used. Series WARNING • 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. • Be careful not to let the cuffs of your clothes get caught in the chain while riding, otherwise you may fall off the bicycle. • Read these Technical Service Instructions carefully, and keep them in a safe place for later reference.

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 - 0.5mm. Chain position Largest sprocket Smallest chainring Pro-Set alignment block 4. Cable adjustment using the intermediate chainring When making the cable adjustment, place the chain on the largest sprocket for the rear and the middle chainring for the front. Note: There are 2 derailleur positions for the intermediate chainring. When making the cable adjustment, make sure that the derailleur is in the inner side (toward small chainring) of the two positions. Locate the derailleur to this position by shifting from the largest to the intermediate chainring (recommended) or by shifting from the small to the intermediate chainring, then gently press lever (b) until a small click is felt (to position the derailleur to the inner side of the intermediate chainring). Adjust the cable tension by using the outer adjustment barrel so that the clearance between the chain guide inner plate and the chain is 0 0.5 mm. SM-SP17 Chain position Largest sprocket Note • 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. • Use the CN-7801 / CN-6600 / CN-5600 with the FD-6703 / FD-5703. • 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 nextlarger rear sprocket or the one after.

Trimming mechanism adjustment and checking 45mm 2. Connection and securing of cable While pulling the inner cable, tighten the wire fixing bolt with a 5 mm allen key to secure the cable. Front shifting Tightening torque: 6 - 7 N·m {52 - 60 in. lbs.} While turning the crank arm, gently operate lever (b) and check that the front derailleur moves slightly toward the smallest chainring. If the front derailleur moves by a large amount and the chain is set onto the smallest chainring at this time, loosen the top adjustment bolt by 1/8th of a turn. Then, after returning the chain to its original position, adjust and check the trimming mechanism.

Chain Installation of the front derailleur 6. Troubleshooting chart Adjust and then install the front derailleur as shown in the illustration. Do not remove the Pro-Set alignment block at this time. 3. Top adjustment Pro-Set alignment block Technical Service Instructions Chain S (ø28.6mm), M (ø31.8mm), L (ø34.9mm) Front chainrings • For smooth operation, 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. • 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.

(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 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 bolt 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 bolt clockwise (1 or 2 turns). If the chain falls to the bottom bracket side. Tighten the low adjustment screw clockwise (about 1/2 turn). 3mm Front derailleur The level section of the chain guide outer plate should be directly above and parallel to the largest chainring.
