Sorry for what is likely an easy question. I have Ultegra Di2 R8050 - and just changed my cassette from an 11-28 to 11-30, which I understand is doable within the short cage rear derailleur hanger.
After changing, I can tell the alignment of the chain is just not "perfect" as it was before.
Do I need to look at adjusting the alignment via adjustment mode, or is there something else I need to be telling the Di2 via the computer connection?
I made the new chain the exact same length as the old one - which I assume is correct too, but please let me know.
