Adjustment of the rear derailleur

ADJUSTMENT

1. Install the battery.

2. Shift the rear derailleur to the 5th sprocket position. Press the button at the junction (A) of the SM-EW67-A-E until the red LED

illuminates in order to switch to rear derailleur adjustment mode. Note that if you keep pressing the button after the red LED

has illuminated, protection recovery operation will begin.

* For details on protection function, refer to ‘Protection function’ on page 38.

3. If shifting switch (X) is pressed once while the initial setting condition is active, the guide pulley will move one step toward the

inside.

If shifting switch (Y) is pressed once, the guide pulley will move one step toward the outside.

The guide pulley can move 15 steps inward and 15 steps outward from the initial position, for a total of 31 positions.

When adjusting, the guide pulley will overrun slightly and then move back in an exaggerated movement so that you can check

the adjustment direction. When checking the positions of the guide pulley and the sprocket, check at the position where the

guide pulley finally stops.

4. While turning the front chainwheel, operate shifting

switch (X) to move the guide pulley toward the inside until

the chain touches the 4th sprocket and makes a slight noise.
