mag wheels

So I looked through all the old threads to not much avail. I got these mag wheels which are disc brake compatible, but I'm not sure what kind of adaptor will for with the 44t sprocket... I read on here I may need to downsize cause there may not be much clearance.. any help, suggestions or simple...

I did not see a review for the wheel set I am looking at. Did not see a home page for wheel master...
