The 2018 Teammachine SLR01 Disc Team with Dura Ace Di2 is claimed to be 15.5lbs (=7.0kg).
So with Ultegra Di2 instead of the Dura Ace Di2 you would add approx. 250-260g and the DT Spline instead of the DT Dicut would add approx. 50g. So it should be approx. 16.09 lbs (=7.3kg) I would say.
I would guess around 7.5kg without pedals.
TonyM left out the heavier bars and saddle.
Woah, ok. What am I likely missing then?

I guess I am missing tubing/cables? But that'd be included in the groupset weight surely?
