Nice Rack! ;-)
I purchased this as a replacement for my Thule rack. The Thule I had would not work with my full-suspension mountain bike, so I got this style of carrier. The Swagman is well built, solid, and keeps my bike sturdy, especially when on rough roads. The width of the tire rests fit my fairly wide tires, though I'm not sure you'd get a "fat" bike on this. I also ended up purchasing the matching locking hitch pin to secure the rack against theft and love it as well.

It seems to be a very good bike rack. I enjoy the light weight. I take the bike rack after every use. Could included a 5/8 inch locking pin, instead of the 1/4 inch pin. Do yourself a favor and read the instruction booklet before you remove the rack and try to put it together. The rack is packed for easy assembly the way it is packed. To install the long bolt on the rack(you will figure it out when you put it together),I had to flip over the rack to align all the holes.
