Change where you need it.
One of the driving forces behind the electronic shifting concept is the ability to place buttons in places that are impossible with conventional cable and housing systems. Designed to be mounted in the drop section underneath the handlebar tape, the Shimano Di2 Remote Switch SW-R610 can also be placed in other locations.
When placed in the drops, however, it allows you to make gear changes when climbing or cheating wind. A small hole can be cut into the bar tape so the shifter tabs are accessible. The Shimano Di2 SW-R610 Remote Switch is not backwards compatible with the Dura-Ace 7970 Di2 derailleurs or wire kits. It compatible with 6870, and 9070 Di2 systems. It plugs into the second port of the Di2 levers, and can not be used in conjunction with TT shifters.

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|

Even nicer than the climbing shifter!
- Familiarity: I've put it through the wringer
Such a nice touch, Can be accessed from the hoods with your thumbs if you're like me and climb in the hoods mostly.
Not just for sprinters!
Aside from the Di2 system itself, the remote shifters are the best improvement I have made to a bike! Being able to seamlessly shift the rear derailleur while keeping your hands comfortably in the drops, these are only way to fly. Mount them wherever it's comfortable, plug and play!
ANSWER BOTH PLEASE
1. Will these plug into the 5 port junction?
2. Is this the price for 2 or 1 shifter(s)?
These units actually plug into the shifters and not the junction box. You will have to unwrap your bars and pull the hoods back to install them. The Ultegra 6870 and 9070 alike have three ports for cables, of which these plug into the bottom port especially made for sprinter shifters. The set here comes with two shifters, replacement double sided tape strips, and a template to cut your bar tape to size. Hope this helps.
