Headset is OEM on the KG381 (Cane Creek KG with Look m-6xl top cap) so suspect the bung is too.
It seems to be an expander but I can't work out how to engage the mechanism. Looking down the hole, it's threaded for the top cap bolt all the way. Allen keys find nothing beneath what I can see.
I've got the same bike and setup. The metal washer you can see should lift out, and there should be a spring underneath. Once there, you'll be able to see the expander.
Does anyone know how to remove this steerer bung?
