You can definitely add di2 satellite shifters to 12 speed shimano. I added the SW-R9150 satellite shifter to my basebars. That gave me two button manual shifting on my basebars. To get the Di2 system to recognize the new satellite shifters, I had to bring the bike to a local bike shop. They needed to update something with my 12 speed Di2 to recognize the new satellite shifters. After the shop had my Di2 recognize the satellite shifters, I was able to program the buttons using the Shimano phone app. I set up the basebars for manual two button shifting for the front and rear derailleurs. Then the single buttons on the aerobars were configured to shift just the rear derailleur. This works great. I only shift the front derailleur when I am on the basebar anyways. Hope this helps.
That’s arwsome
This is exactly what I’m after , but I’m told the 12 speed won’t recognise the shifters
How old is your 12 speed and or firmware ?
Also where did u place the shifters ?
What sort of bike , a pic would be super
Thanks
12 speed Shimano will absolutely recognize supported satellite shifters. In fact, Shimano's current TT/Tri setup is using a "satellite" shifter for the aero extension buttons. These are the SW-R9160 shifters. You can add SW-R9150's to the system and mount them where you want.
The current Shimano mix of 11 and 12 speed Di2 components for TT/Tri setups is a PITA. I too despise the synchro shift only approach. Here is the official Shimano compatibility table for 12 speed Di2.
https://bike.shimano.com/...CC%205.1.6-00-EN.pdf Under the Switch Units see the box for Dual Control Levers SD-50 for the components supported for the TT/Tri builds. The one caveat not spilled out here is that the system will only support six (6) total shifting devices. Without hacking components, this basically means that in addition to the base bar brake shifters and the aero extension shifters you can only add two more satellite shifters.
On my wife's Trek SC SLR, I added 2x SW-R9150 shifters and mounted them just below the ST-9180 brake lever shifter buttons using high strength mounting tape. The distance from the SC basebar Di2 access port was too far from the brake levers for the satellite shifter wires. So I cut these and extended them using extra lengths of e-tube wires/ports.
I don't remember running across issues recognizing the new satellite shifters. I always update my Di2 components to the latest firmware as a first step. I also have both versions of the Shimano Di2 USB programmers and can't remember what I had to use for the updates and programming. If you can't get it done yourself, I'm sure a LBS can get it done for you. These were setup to function the way the prior generation, two button Di2 basebar shifters worked - lower (satellite) button = higher gearing and upper (brake lever) button = lower gearing. Left side = FD and Right side = RD. Aero extension shifters control RD.
Hope this helps.
