Light and disc bike tend to not go hand in hand, unless you want to shelve out a bunch of money all carbon parts.

Where did I see 500+ gr for hydraulic shifters? Maybe ultegra non-di2 hydraulic? I forgot...
All non-series Shimano hydro shifters are over 500g, including ST-RS685 (~646g) and ST-R785 (~510g).

Sorry @Klaster_1...should have linked your bike...it's one of the lightest disk bikes on here
At least, some recognition
Woah! No wonder I was so shocked when I removed my RS-685 levers for the first time. I didn't put them on scale, but I thought "Wow! These are so heavy- why?? Hmmm...cast aluminum bodies..." Interesting to know how much weight these shifters are adding.

Ultegra r8070 di2 hrd levers 360gr/pair
Ultegra r8020 mechanical hrd levers 554gr/pair
Duraace r9120 mechanical hrd levers 538gr/pair
Duraace r9170 di2 hrd levers 320gr/pair
It's ridiculous that the shifting mechanism weighs 200gr over electric. On Sram red it's 20gr.

Just got my new Izalco max disc
with ultegra di2
. It is all stock
apart from Pro Vibe Alloy Bars, Pro Team Bartape and Pirelli Pzeros. My scales say 8.1kg but surely that isn’t right for one of the lightest disc brake frames in the world.
You can shave some weight by significantly upgrading the wheels, a little bit by switching to TIME or Speedplay pedals, and a little bit more by going to a full carbon cockpit. There's some further small savings to be had by going to carbon cages and Ti fixtures. Finally, the obvious, you could also go up to DA Di2 or SRAM Red.
Try making an Excel sheet carefully listing out your entire build, including cables, headset and everything, and try to get that total to show what you actually weight the bike as. Then in a column next to that, play with swapping out various things so you can see what it does to the weight per the cost of said upgrade. I do that quite often when faced with these kinds of things - or - when fantasizing lol.
