Let's try to fix this ;-)
I think the first thing I would do would be to connect the bike to a windows computer, start e-tube project for windows and then check the current RD adjustment setting. I would reset that to '0' and start over.
Also, e-tube project will tell you (if you go to RD adjustment) what gear it thinks the rear derailleur is in. Double check this to make sure yours isn't offset by one gear somehow.
It shifting onto the 11T is not something that would worry me. The feature that blocks the smallest sprockets (Gear Position Control) can be disabled and is only enabled for some cassette / chain ring combinations anyway
.
If it has worked just fine until last week I would also double check the rear derailleur hanger. A Di2 bike doesn't really go 'off' on its own.
Hey Terry, I checked the mech hanger first, and I put on a new one, that was my initial thought.
I know that it is not supposed to shift into the last two cogs on the cassette when on the small ring in front, which is why I think there's definitely something in the software of the rear mech, or the shifter.
I only have a macbook, but I'll see if I can get 'etube' to work on it, thank you verry much for your suggestions, I'll post back in the next few days when I get an opportunity to work on it.
