Adjustment

SIS adjustment

Turn the cable adjustment barrel clockwise to reduce cable tension

until no noise is heard from the chain rubbing the sprocket.

Return the shifting lever to its original position (the position of the 2nd

sprocket counting from the smallest sprocket, with your finger released

from the shifting lever), then turn the crank.

NOTICE

• If it is touching the 3rd sprocket counting from the smallest sprocket and making

noise, turn the cable adjustment barrel clockwise slightly to tighten it just

enough until the noise stops.

Operate the shifting lever to change gears while turning the crank, and

check that no noise occurs in any of the gear positions.

TECH TIPS

• The rear derailleur will not gear shift properly if the derailleur hanger is not

straight. Use TL-RD11 to check whether the derailleur hanger is straight or not.

Set the switch lever in the ON position and check that the gear shifting

is smooth, consistent, and that there is no noise in any of the gear

positions while riding the bicycle.

If gear shifting from the largest sprocket becomes slow with the switch lever in the ON

position, adjust the guide pulley slightly further away by turning the B-screw.
