Have seen the photo, how on earth did you break it?
yes thats Di2.
I don't really know. I was just riding along went to shift to the small ring, heard a strange noise and it wouldn't shift, stopped and noticed the damage.
I did fall over on that side, just under a year ago. I guess it could have weakend the metal, or the chain jammed. Fortunately, I wasn't too far from home.
