Feels like Im learning about bikes all over again after a recent s/hand CX bike purchase. All good fun though! 🙂
Is this bung removed with an allen key or such? The threaded section seems to have an allen key cutout too....I think.
Thanks for info guys!

by the looks of it just an allen key in that top hex you see. The top cap bolt will go down into that hex to the thread.
The Allen key bolt will drive into an expander bung inside the carbon steerer tube and unscrew using a suitable size Allen key
Thanks guys, as always I knew you lot would know for sure. 🙂
IME, the bung isn't normally visible above the stem. Watch that it doesn't stop the headset being adjusted properly; I assume that there's a spacer above too??
Don't undo that bolt completely as the expander wedge may fall off the bottom. Just unscrew it a bit and if necessary give it a gentle tap to free the wedge.
