weight in total is one thing and weight distribution is another.
If you were going for a light as possible and best possible weight distributed build, you’d be looking at putting together a 4-7x2 drivetrain.
I don’t know if you can still source a freehub that’s both robust enough for how you intend on riding and is optimized for less than 8 cogs.
The industry isn’t there right now. If you can be satisfied with 1x and never need/want a granny/bailout gear, just do 1x.
Or do the mullet or reverse-mullet (I’m not cool enough to know which it is. I think it’s dumb to not call it extended range 2x): 1x rear + 2x front with whatever ring you would be comfy using for the middle four cogs 90% of the time and a bailout ring.
