    Quick update for anybody with the same issue.

    1. I can confirm that the latest version of the PC software has the ability to alter the FD setting (I was using out of date version!!)
    2. Setting this to 59/39 will resolve the issue of not being able to use the 12T and 11T cogs while on the small ring, however there is one additional setting you need to make for this work. There is an additional setting called "Gear Control" on the same page. Make sure this is set to "off"

    Thanks to all for suggestions, additional gears now available for those who like using them

    regards

    9150 Rear Derailleur & Chain

    I'm sure you tried this, sgc, but just to be explicit, what happened when you left the FD as 50/34 but turned off "gear control?"

    Didnt try this, everything I have read to date said change the FD to 53/39 so I assumed (perhaps wrongly) that others had tried the 50/34 option? It isnt too much hassle to set it up with the 50/34 option, so will see if that works and report back

    Yeah, that's what I read, too, but your post was the first time I've read of the "gear control" option. I'm wondering if that new option is solely responsible for disabling cross chaining. The older di2 groups (6870, 9070, etc) don't have the "gear control" knob, and they allow full cross chaining.

    I'll give it a try tonight and see if the theory works?

    Curiosity got the better of me!
    Only those options with a gear difference of 14T or less will work, ie 54/42, 55/42, 53/39, 52/38. If you choose any other option, the gear control option is greyed out and will not allow you to make any changes. So one of the initial comments about the 14T differential is correct.

    regards

    Little late to the game on this. Have been running Ultegra 6870 Di2 with internal battery BTR2 for years but upgraded to 8070 derailleurs. Using the PC interface but it doesn't provide me with options to modify the gear ration in order for me to still use first two gears while in the small ring. This is discussed in-depth in the thread above. Am I correct that I'm not seeing this option because of the BTR2 battery and that I need to upgrade that to the DN110?

    The PC version of the ETube app does allow you to change these settings. I think 'sgc' confirmed this in this thread, and I've done it myself.

    I don't have the app available to look at it, but it's in there.

    I have the pc connector and app, have connected to the bike and made the necessary changes, including the gear control and the bike still won't allow the full spectrum of gears!! Is there anything else that needs to be done in order to get this to work?
    Cheers
