fd-6870 auto-trim - does it work on v2.5.2 with 10sp rd?
@DeeHubbs
thanks. I try archived all possible versions, this one are missing.
I will try to mix 10sp road di2 rd with mtb di2 fd and fd-6870.

My 10sp FD fully trims with my 11spd RD. The trim points are matched to the RD perfectly.
I have not personally mixed the Road and MTB, but from what I understand is the v2.5.2 is the last version before they wrote the firmware to not allow mixing of different series. I bet that MTB and Road would play.
The tricky part is once you update the software you can't rewrite it backwards. I currently have a stash of parts that I purposely have not updated past v2.5.2 to be able to use them a s mix and matches.
But now that they have released the CS-R8000 11-34 cassette I can use all those old 10spd wheels again and not worry about having a 10sp RD. (I could even run a 53-39 big boy chainring here in the mountains :wink: )

As far as i know, and according to the Shimano compatibility charts,
Road and MTB mech's can't be mixed on the same bike, shifters is not a problem but the mech's don't work in a mixed system.

FD-6770 - does it have electronic adjustment like FD-6870 or it only uses 2 bolts for adjusments?

This may have been answered and I did not go far enough back in the forum, is it possible to downgrade a dn110 battery using firmware 4.0.5 to something I .can use with the ew67a? Have an ultegra 6870 with this grouppo and battery is dead so looking for ways to keep it internal. I don't need the amazing things the new stuff does, just my old sweet system. I saw I need the pce1 to do the downgrade but maybe help figuring out which files to expunge and swap and rename. Thanks

We've heard from a number of you that 6770-equipped bikes behave oddly after updating it with version 3.2.1 of E-Tube Project app and the component firmware bundled with it.

We are advising dealers not to update the firmware on 6770-equipped bikes until this is resolved with a future version of e-tube Project.

6770 hasn't had new features added via firmware in many years - probably since multi-shift capability (the ability to hold down the button and have it move across the cassette 2, 3 , or more positions). So there's not much reason to update firmware for 6770.

If you have experienced an issue with a 6770-equipped bike after a firmware flash, please contact our Customer Support Team: 800 423 2420 in the US, or 877 377 5211 in Canada.

The 6770 bug fix needed more development time, so we expect that to be fully addressed in v. 3.3.1. Until it's released, we continue to advise you not to update firmware on working 6770 Di2 bikes. If you have a borked 6770 bike? Call our Customer Service team. 800 423 2420 in the US, or 877 377 5211 in Canada.

Lol. Given nobody except dealers got those messages, I guess there might be a few"borked" ones out there.
