Double click your control box. Twice.

can i get rid of this.. in the ETube software i cannot seem to find the disable these types of shifting..
Double-tap the button on your A junction box. The LEDs should flash. 1 flash is manual, 2 is shift mode 1, 3 is shift mode 2. Modes 1 and 2 are your synchro/semi-synchro modes that can be set via the app if you have wireless, or via PC through the wired interface.
Just double-tap it until you get back to 1 flash and you should be good. You may also be able to do this via your GPS head unit assuming it supports it. I think Garmin 520/820/1000 are the only ones that currently do though.

I'll leave it up to you to figure out the other 30%. If you are in any way offended, that's on you.

Double-pressing the button on your bikes junction box (when the bike is not plugged into etube) will cycle through the 3 shift modes and then flash the current shift mode.
Also press and hold a shift button and the battery light will indicate charge then the lights will flash the current shift mode.
One flash for manual shift, twice for semi-sychro, three times for full synchro.

Try disconnecting the battery. And reconnect. If no joy, then;
1. Disconnect all components, leaving just the battery and control box.
2. If that's OK, add components back in one at a time.
3. Update them as you go.
4. Cross your fingers and hope.

Not that I know of - maybe someone else will chip in.
Do you have the PCE-1 diagnostic tool?

I created an account just to search for and confirm this. My frustration with this knows no ends. I won't even talk about all the things I did to "upgrade" to the configuration I have now from the factory set up on the Cervelo S5 Team LE I just bought. It makes me want to change cassettes...

Just a note that may help people in the future. I swapped out my non Bluetooth d-fly for the new Bluetooth one, and on the way managed to completely toast my set up. Only the left lever was registering even when I plugged my PC in.
I eventually solved my issues after a great deal of panic by unplugging everything that went into the junction box and connecting the PC, running E-TUBE a few times and then plugging components in one at a time, closing and restarting E-TUBE after each component. Luckily all good now, but there was an hour or two of complete dread!

As of last week, the way to avoid that was to tell the E-Tube software that you are running an 'allowed' combo, but that will throw the numbers in the gear ratio chart, leaving you to do your own math. They did not tell us what the tooth difference limit officially is, but 53/39 is allowed and 50/34 & 52/36 are not.
So, I tried to setup semi-synchro today with the new firmware update and kept getting the following error:
"bike has a gear structure that cannot be configured"
I'm guessing it's due to this, as I have it configured for 52/36 (actually running 50/36 elliptical). Anyone else seeing this error? Shimano is giving absolutely no information in the app as to what "gear structure" it is that cannot be configured.
Did you find a solution to that message?

Sorry for the delayed reply, been a while since I logged in. So I got it to work, forget exactly how. I might have just set it to a "supported" configuration. Ended up going back to normal shifting. Didn't really like the synchro or semi-synchro.

I'll leave it up to you to figure out the other 30%. If you are in any way offended, that's on you.

I also reverted back to semi-synchro as synchro shift mode would not allow me to use the largest rear cog to top a hill without shiting to the small chainring, which often meant shifting back to the big chainring 10-20 seconds later.

This Synchro Shift feature is a really frustrating thing... First the R 9150 RD doesn't take the slack on all gears even though it looks like you have an anchor fixed to the rear of the bike (not to mention how difficult it is to remove the wheel-wasn't it that the new standard was meant to make it easier?)
Then the function is downright awkward. The shifts to the small ring are slow like b*****s and it will stay on the big ring until the chain is at 90 degrees with the road?

Hi there, long time lurker, first time poster here looking for a bit of help.
I've just upgraded to lateset battery and wireless unit. I'm trying to set up syncro or semi-sync shifiting. It will only allow me to do this if I select 52/36 & 11-28. For every other combination of chainrings or sprockets I get the message "the bike has a gear structure that cannot be configured". I feel like I'm doing something wrong as, surely, it should work with other combos.
I have upgraded the firmware on all components and using the iphone app and e-tube software.
Any advise on where to look greatly appreciated.
Cheers,
Pete
