Oops, were we supposed to see that?

I would post a photo of that derailleur, but this site doesn't host images.

Shimano wireless would make me happy.

This thread is nearly worthless without pictures!

Yes, it does, just need to know how to use the site.

Click on "User CP" in the header/user bar then click on "Pictures & Albums" then click on "Upload Pictures" then click on Choose File" then click on "Save File" find the image, click on the image and copy the "BB Code".

Paste to a new message and post!

Or you could just do a screen shot

That is just stupid to have to jump through three hoops to upload an image. Here is a small image.

The mechanic sitting next to you doesn't know his terminology. Both of the current Dura-Ace 9100 rear derailleurs (mechanical and di2) are "shadow" derailleurs.

That looks like the ****

I don't think it's wireless. There is no battery.

[glepore]

Don't think its a clutch, the Ultegra version has a switch to engage/disengage the clutch that isn't in the shot. I looked at it carefully on the replay coverage, couldn't see a wire...doesn't mean its not there. The upper link does look different than the current 9170.

Might not need a battery if shimano follows through on their patents to make power via the pulleys 😄

[Jaybee]

maybe there is a wire that arcs down from just underneath the junction of the chainstay/seatstay and follows the curve of the hanger? Maybe I'm just imagining it?

Yes.

Idk, just looks like 91xx with a modified hangar, if that.

Looks like a standard Scott installation of a Di2 9150 rear derailleur:
