Just took this new gravel bike out of the box today! When putting it down I realised it makes a strange plasticky banging noise. Even at very gentle (lateral and vertical) impact. Any idea what it might be?
I removed all the wrapping etc and the wheels roll normally, Shifting works as well.
Seems to come from bottom bracket or rear derailleur area, though unclear.

Valve stem nut
Edit nm, I see it’s near the ground and wouldn’t vibrate like that.
Maybe some material from machining is trapped in the rim.
Definitely presta locking
