What's CPSC? Child Protective something? In fact, you see one MTB in the rack there, but for the picture I did have to put in that bike but not another, or maybe it was front wheel not back, because I had a MTB tire that was just a leeeetle bit too big. Probably could force it in though.
In the pic, the rack part is not even screwed into the base or the stays screwed on yet; since I'm moving I decided to keep it flat-packable and finish it off in the new place. I expect it to be quite sturdy -- and squeeze 3-4 more bikes in there!
