Note
* Adjust the RD-T300 Rapid Rise rear derailleur (reverse
spring type) from the low side.
* Always be sure to use the sprocket set bearing the same
group marks. Never use in combination with a sprocket
bearing a different group mark.
* Because the high cable resistance of a frame with internal
cable routing would impair the

has some length to spare even
when the handlebars are turned

Furthermore, check that the
shifting lever does not touch the
bicycle frame when the
handlebars are turned all the
way.
* Grease the inner cable and the inside of the outer casing
before use to ensure that they slide properly.
* For any questions regarding methods of installation,
adjustment, maintenance or operation, please contact a
professional bicycle dealer.

Turn the cable adjustment bolt
counterclockwise to loosen it
until the chain touches a
sprocket and generates noise.
Best setting
The best setting is when the cable adjustment bolt is
tightened (turned clockwise) until noise occurs without
lever (A) being operated, and then loosened (turned
counterclockwise) 90 - 180 degrees from that point.
Operate lever (A) to change gears, and check that no
noise occurs in any of the gear positions.
For the best SIS performance, periodically lubricate
all power-transmission parts.
Replacing the indicator
1. Press button (B) to set the lever to the lowest position.
2. Insert the pin of the indicator gear into the hole of the
winding reel.
3. Move the indicator needle to the [1] position.
4. In the condition in step 3., place the indicator on top of the
brake lever bracket. Be careful not to let the indicator needle
move at this time.
5. Secure the indicator with the two indicator set screws.
