Koxx frame with kh wheelset

So, I just bought myself a alien backflip frame, to put on my flatland wheelset, but I had a bit of trouble getting it on. At first when I put it on, it wasn’t wide enough, so the frame would rub against the hub. In order to get it to work I had to grind down the side of the barring holders.

Has anyone else had problems like this?

I think it’s the kh barrings that are different than the koxx ones, because the frame seems to fit in a bit loose compared to my kh frame.

what eyar KH hub is it? my 2009 hub worked (with blck pressedflang) nut silver 2010 flange and blue 2007 dont work im thinkin becuase its too wide…
