Dear Bicycle Dealer,
As announced in our previous e-news, please find below the technical information and tips and
tricks about the electronic DURA-ACE.

Di2 batteries and chargers
There are two different types of batteries available for the
E-tube components, like DURA-ACE 9070, ULTEGRA Di2
and ALFINE Di2: one for mounting inside the seat post
(SM-BTR2 internal) and one for mounting on the frame
(SM-BTR1 external).
The internal battery is charged via a USB port using a special
charger SM-BCR2 on the handlebar junction box. The external battery is removed for charging in the SM-BCR1 charger.
Note: The chargers are not interchangeable.
Battery for mounting on the frame: SM-BTR1 external
Required charger: SM-BCR1
Battery for mounting in the seat post: SM-BTR2 internal
Required charger: SM-BCR2
Di2 Rear Derailleur and Front Derailleur
Adjustment of the stopper bolts
Trouble-free, precise and light-action performance is only possible when the
stopper bolts on the front and rear derailleurs have been properly adjusted.
Rear derailleur: Adjustment of the stopper bolts
“Low” adjustment
Shift the chain to the largest sprocket, and then tighten the
“low” adjustment bolt until it touches the stopper.
If the bolt is tightened too much, the motor will detect a
problem and gear shifting operation will not be carried
out correctly. Symptoms of this are:
• Not possible to shift into lowest gear
• Noise
•B
attery gets used up fast (motor draws too much power)
“Top” adjustment
Shift the chain to the smallest sprocket, and then tighten the
“top” adjustment bolt until it touches the stopper. From this
position turn the top adjustment bolt anticlockwise one
turn so there is a clearance of about 1 mm to allow for
overstroke of the rear derailleur.

Front Derailleur: Adjustment of the stopper bolts
“Low” adjustment
Shift the chain to inner (smallest) chainring and the largest
sprocket. Use a 2 mm Allen key to adjust the bolt for lowest
gear so that the distance between the chain and the inner
plate of the FD cage is 0 – 0.5 mm.
0 – 0.5 mm
“Top” adjustment
Shift the chain to outer (largest) chainring and the smallest
sprocket. Use a 2 mm Allen key to adjust the bolt for highest
gear so that the distance between the chain and the outer
plate of the FD cage is 0.5 – 1.0 mm.
0.5 – 1.0 mm
Di2 fine tuning of front and rear derailleurs
Both then front derailleur and the rear derailleur are pre-programmed, therefore adjustment
between the different gears is not required. For fine tuning (calibration), the derailleurs have
a special programme which allows them to be properly adjusted.
Rear derailleur adjustment
1. Install the battery.
2. Shift the rear derailleur into position at the 5th sprocket.
To activate the rear derailleur adjustment mode, press the
button at the junction (A) of the SM-EW90 for 2 seconds
until the red LED lights up.
4. W
hile turning the crank arm, press the button (X)
repeatedly until the chain rubs against the 4th sprocket.

3. By pushing the shifting buttons on the right shifter, the rear
derailleur will move inward (X) or outward (Y). The rear
derailleur 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 into the final position so that you can check the
adjustment direction.
5. Then press the button (Y) 4 times. The guide pulley is
now in the proper position, centred under the 5th sprocket.

6. After completing these adjustments, press the button at the
junction (A) again for two seconds until the LED goes dark
to get out of the adjustment mode.
7. Check all gear positions again. If you hear any rubbing
noises, repeat the adjustment procedure from step 2
onwards.
Front derailleur adjustment
In the new DURA-ACE it is now also possible to calibrate the front derailleur.
1. Install the battery.
2. Important: Shift the chain to the largest chainring and
the largest sprocket.

from the initial position, for a total of 25 positions. Optimum
adjustment is a clearance of 0 – 0.5 mm between chain and
inner chain guide when the chain is on the small chain ring in
front and largest sprocket in the rear.
