I just ordered a Saris Freedom Superclamp 4 bike rack. I need to get a hitch for my death cage to mount the rack. I know fuck nothing about death cages and related accessories. All I know is that I need a 2" receiver. Any suggestions on what specific type to get (I believe they come in different "classes" or strengths/qualities), where to buy, etc? I asked /o/ but those faggots weren't helpful.

>inb4 only faggots put bikes on a cage
I often ride from home but I need a way to carry my bikes when I do long-distance travels (as in driving to a different state).
