General Safety Information
WARNING
• Obtain and read the service instructions carefully prior to installing the parts. Loose,
worn, or damaged parts may cause injury to the rider.
We strongly recommend only using genuine Shimano replacement parts.
• Read these Technical Service Instructions carefully, and keep them in a safe place for
later reference.
Note
• Operation of the levers related to gear shifting should be made only when the front chain-
wheel is turning.
• 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.
• Use a frame with internal cable routing is strongly discouraged as it has tendencies to
impair the SIS shifting function due to its high cable resistance.
• A special grease is used for the gear shifting cable (SIS-SP41). Do not use DURA-ACE
grease or other types of grease, otherwise they may cause deterioration in gear shifting
performance.
• 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 opera-
tion, please contact a professional bicycle dealer.
Note when using the reach adjustment block (Pad spacer)
When installing the 8-degree reach adjustment block, use an anatomic-type handlebar.
If a round-type handlebar is used, the cable stroke may become too short and this can
result in insufficient braking force.

Shimano Total Integration Features
The Shimano Total Integration TIAGRA series features a dual action control lever which
actuates the brakes like a conventional brake lever, and shifts the gears when moved inward
toward the center line of the bicycle. Gear shifting is now possible without ever taking your
hands off the brake hoods or drops.
In order to realize the best performance, we recommend that the following combina-
tion be used.
