Shimano Di2 Setup Using E-Tube App: Synchro Shifting, Gear Changes & More! 

Good to hear! I couldn’t find a good video on this myself, so I just decided to create my own.

Awesome! Glad you liked it.

Glad you found it useful. Cheers.

Glad you could use it. Thanks for watching!

Glad to hear! I love using the hood buttons to change screens on my Garmin 1030.

Glad to hear it!

Thanks! I was surprised it was so difficult to find any tutorials on the E-Tube app as Di2 is so common now.

You cannot turn off Synchro Shift with the app. You do it on the bike by cycling through to “Manual Mode” using the function keys. The process I talk about at time stamp 12:06

I recall experiencing a similar problem, but the cause may be different than yours. Not sure. In my case, it was simply that I wasn’t using the latest firmware. I updated the firmware and both front and rear derailleurs started working fine.

No. You aren’t doing anything wrong. You’re exactly right. When you are in the eTube app and setting up the micro-adjustments, you cannot shift gears at the same time. You need to exit the app for that and get out of pairing mode. For micro-adjustments, you may find it just as easy to set it up NOT using the app, but just using the junction box settings on your bike. I’ve always found that if I follow Shimano’s instructions on how to properly set the rear derailleur step adjustments, it works without any further tweaking. That process is basically as follows: - Shift rear derailleur to 5th largest sprocket. - Shift front derailleur to small chainring. - Press button on Junction box until LED illuminates. - Turn the cranks and then press your shifter button until you hear it rubbing against the 4th largest rear cog. - When you hear the slight chain rub, press the other shifter button 4 times to move derailleur in the opposite direction back towards the 5th largest cog. This should centre the pulley wheels under the cog perfectly. - Press junction button until red LED turns off. - Shifting should now be set properly. If that isn’t making for clean shifts, I would think there is something else up. Like maybe a bent derailleur hanger. Sorry if this isn’t all that helpful, or if I gave you way more info than what you wanted :)

@@bikesbymike Thanks a lot Mike for your detailed answer! Hard to find on yt. My shifting is perfect I only have adjust it forth and back when I put my bike on the Wahoo kickr trainer which has a sunrace cassette. I can’t get it as smooth as Shimano, might be the trainer as well.

@@simonwarmer8777 Oh. I see. So you are doing more frequent adjustments than the typical Di2 user. It must be the different cassette and/or the cassette spacing on the trainer is slightly different than what you have on your bike.

I don't have experience with the Bolt, but GPLama has a good video on this... ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-pgGITe1_OQ0.html

GPLama covers the shifter firmware update issue here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-7k8IVKGBUds.htmlsi=evqF9MQ8uck2CYfm. He does mention that a wired connection is required for Dura Ace and Ultegra, but I just tried my 12-speed Dura Ace Di2 and I believe it allowed me to update all firmware updates wirelessly. It's not showing that a firmware update is needed for the shifters anymore, so I assume it did it ;) As for the gear maintenance log, if you are referring to the "Gear usage rate" which shows the % of shifts on each rear cog, then no, mine is not working. It's just showing 0% for each cog.

Hmmm. I don’t know why that’s happening. Are you using the iOS version? Maybe there are slight differences between platforms??

@@bikesbymike got it. I was looking at the semi-synchro control, not full synchro.

Hard to say as it could be several things. First thing is that for all Di2 models except 12-speed, you have to have the Shimano D-Fly Wireless unit attached to your bike. This unit allows the Di2 to pair with the app. If you have that already, you should have all the hardware you need. Make sure you have the latest firmware installed and also make sure your Di2 is in pairing mode as I show in my video. Those are the big ones I can think of.

If it’s a brand new bike where the Di2 hasn’t been used, sounds like an installation problem. Just wondering if the front derailleur low and high limit adjustments have been set correctly. That’s one possible options but there are others.

Yes. The options available for the X, Y & A shifter buttons on each shifter (or just X & Y in the case of 105 Di2) are the same. So you could assign the “Function” option to either the X or Y lever shifter on the 105 to control the Synchro mode on-the-fly.

@@bikesbymike thanks a lot.

@@bikingchupei2447 Glad to help!

Just two things come to mind. First, make sure your Di2 system has the hardware necessary for Bluetooth capability. If you have the new 12-speed Di2, the Bluetooth module is already built into the rear derailleur so you don’t need anything extra. With the 11-speed version like what is shown in my video, you need to purchase and connect the Shimano Wireless Module - EW-WU111/EW-WU101. Second, it’s possible the firmware isn’t up-to-date and causing connectivity issues. If you can’t get the wireless connection to work, an alternative is to use a hardwire connection between your laptop/desktop and your Di2 as described here… ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Ip1EiTNg2So.html Shimano offers a Windows desktop app that works quite well if you have a PC and the Shimano connection cable. Here is the link to the Windows download… bike.shimano.com/en-US/e-tube/project.html You will then be able to check that your firmware is up-to-date and also do all the things you can do with the E-Tube smartphone app. Hope this helps.

@@bikesbymike thanks for the detailed reply. I've had the wireless module fitted by my bike shop (or at least they said they fitted it...) so perhaps I just don't have the firmware update to finish everything off. I'll try connecting to my laptop and see if that helps.

I’m not certain what’s happening at your end, but here are a few things to try. If you haven’t used the app with your Di2 before, you will need to “register bike or power meter” just for the first time. This allows the app to set up a profile for your Di2, and more importantly, to search for your Di2 components. If it’s searching and stalling like you say, it’s usually one of four issues. 1) Your Di2 isn’t in Bluetooth connection mode. For the new 12-speed version, this is activated by pushing and holding the button next to the rear derailleur for 0.5 to 2 seconds to make LED flash blue. 2) Bluetooth connectivity isn’t activated on your smartphone. 3) E-Tube is looking for the PassKey, but you should get prompted if it needs it. The default is 000000. 4) The latest firmware update hasn’t been downloaded to the app. The app will prompt you as soon as you open it to download the new firmware if one is available. Always run the latest firmware if prompted. If none of these four fixes work, I’m not sure what the issue is.

You also have to give permission to the app to use bluetooth when you install it. Somehow I missed that the first time I installed the app, deleted it and re-installed, then allowed permission and it connected.@@bikesbymike

You can set up your Synchro settings through the eTube app, but you can only change the mode you are in on the bike. A quick double-press on the rear derailleur (for 12-speed) or the junction box (for 11-speed) will switch your shifting mode to the next mode. There are three modes in total stored on your Di1. Manual, Shift Mode 1 and Shift Mode 2. Every double-click sends you to the next mode. For 11-speed, solid red/green is Manual. Double blinking red/green is Shift Mode 1. Triple blinking red/green is Shift Mode 2. For 12-speed, solid blue is Manual mode. Double flashing blue is Shift Mode 1. Triple flashing blue is Shift Mode 2.

If you have the new 12-speed Di2, the Bluetooth module is built into the rear derailleur so you don’t need anything extra. With the 11-speed version like I have, you do need to purchase the Wireless Module - EW-WU111/EW-WU101. An alternative if you can’t establish a Bluetooth connection is to use a hardwire connection between your laptop/desktop and your Di2 as described here… ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Ip1EiTNg2So.html

@@mikemillar795 thanks Mike. My clarity was poor. Connection is no problem using the cable and the desktop app, V4. Using the desktop version, is it possible to reconfigure the default synchro to the cogs I prefer? It seems like I'm unable to make changes to cog selection.

@@kevinmccutcheon7047 I haven’t used the desktop software for a couple years now, but I know at the time I could do everything the smartphone app does, including customization of the gearing (as well as the gear change over locations).

Yes. 105 as well.

All versions of Di2, not just the new 12-speed, but there are some limitations for the oldest versions of 11-speed Di2 which have the ANT+ ONLY (not Bluetooth) battery. You also need to have the D-Fly Inline Wireless Unit for any version other than the newest 12-speed. Best to check the following compatibility chart which clearly shows which Di2 components work with the E-Tube app and what limitations (if any) there are. chrome-extension://efaidnbmnnnibpcajpcglclefindmkaj/bike.shimano.com/content/dam/e-tube/assets/images/contents/project/compatibillity/pdf/en/HM-CC%205.2.0-00-EN.pdf

@@bikesbymike Thank u. I figured out u need d-fly to be able to use the hood buttons sadly. But thanks :)

Works with both. The 11-speed does require the D-Fly inline Wireless Unit EW-WU111 to allow Bluetooth connectivity between your phone and Di2.

Were you able to figure this out? @richardmiddleton7770 My 2020 Domane SLR7 has 11 speed and I press & hold the connect button, the red and green light flash for 2 seconds then turn off. Cant seem to figure it out.

Did you find out what's wrong?
