Is it true that they are only half CF? Outer part CF, inner part alloy? 

I asked specifically that because it indeed looked like his. According to them, the rim is entirely made of CF but received a coating on the inside of the rim. 

In the Shmee video (I know, I know), he shows a stand alone CF wheel towards the end and you see the barrel in CF.  But as you say the inside has a coating.
