Shimano E-Tube Di2 Complete Wire/Power Kit $589.95
Everything you need.
This Shimano E-Tube Di2 Complete Wire/Power Kit is a complete kit and contains all the necessary pieces to hook up your Ultegra 6770 Di2 electronic components. You'll get five wire sections -- front wire harness, downtube, front derailleur, rear derailleur, and battery. The front wire harness has an integrated A junction, but the B junction is a separate unit. You'll get that as well. The kit also includes a battery and battery mount along with a charger and cable.
We have the E-Tube Di2 Complete Wire/Power Kit in a number of wire length options to fit differently sized frames. You can also choose between internal or external. For bikes designed to accept it, the Internal kit will route the wires and B Junction inside the frame tubes. Conversely, the External kit routes all the wires on the outside of the frame tubes, and the B Junction is fastened to the cable guide underneath the bottom bracket shell.

Battery and Wires:
Our Shimano Di2 packages are built for three standard configurations based on battery location and wire routing. First, you'll need to determine if your frame uses an internal or external battery mount, and whether the routing is either internal or external. Below is a guide for which battery, charger, mount, and junction boxes are required for your configuration.
|Battery||Battery Charger||Battery Mount||Junction A||Junction B|
w/ External Routing
|SM-BTR1||SM-BCR1||SM-BMR2||SM-EW90 A/B 3/5 port||SM-JC40|
w/ Internal Routing
|SM-BTR1||SM-BCR1||SM-BMR2||SM-EW90 A/B 3/5 port||SM-JC41|
w/ Internal Routing
|SM-BTR2||SM-BCR2||SM-EW90 A/B 3/5 port||SM-JC41|
The SM-BMR2 battery mount is available in three configurations -- Long External, Short External, and Long Internal. Both Long versions are to be mounted using the bottle cage mounts, while the Short version is designed for Di2-specific frames with either a chainstay or down tube mounting location.
There are two junctions needed for completing your Di2 build -- A and B. Junction A, SM-EW90, is located at the handlebars and available in both three- and five-port options. The three-port option is intended for standard shifting with a left and right hand shifter. If you have the intention of using Shimano's satellite sprint shifters, or a combination of time trial shifters and shifter/brake levers, the five-port junction box will be the necessary selection.
Depending on your frame specification, Junction B (SM-JC40 or SM-JC41) is located either internally or externally at the bottom bracket area. Accordingly, SM-JC41 is designed for frames with internal wire routing, while SM-JC40 is intended for external wiring options.
For your convenience, we've created wire packages for your Di2 build kit in the sizes Small, Medium, and Large. Below, you'll find which wire lengths are included in each kit. Additionally, we've recommended a kit size based on your frame size.
|Down Tube Wire||700mm||750mm||950mm|
|Front Derailleur Wire||300mm||350mm||400mm|
|Rear Derailleur Wire||500mm||550mm||600mm|

is compatible with the levers dura ace?
That is going to be compatible with the new Dura Ace 9070 11 speed, but it is not compatible with the older 7970 10 speed levers.

Does this include the 3 or 5 port junction A? Is it possible to add the TT shifters (SW-R671) to this kit?
