That's all just angling the levers inward, don't think the bars have changed

I think Enve and a few others do stuff like this. Just look at Campenaerts bike.
I kind of like flared bars, angle the levers in and you get aero tuck and wide in the drops for gnarly stuff. Stupidly wide bars, that I don't understand.
Tiny flared bars seem to be the rage in road racing now
