Well;
It didn't break. I did a first ride for it at Jones last night. Also the first MTB ride for my 13yo nephew, so it was more of a training and teaching ride than anything. Lots of junk down after our tornado watch last week too. Anyways, the Fatty rides pretty darn good. Not that much different than the Niner really, when just peddling along. Oh, it is certainly less cush, but other than having no rebound damping, those big tires really give a lot of suppleness. It can be a bit bouncy if you are sitting down, but flying over rougher terrain is surprisingly composed. Floats through the creek crossing and over smaller roots like nuthin. I stayed away from the nastiest trails in deference to my nephew, but did let it fly a couple of times and it seems to ride really well.
All in all this has been a very successful venture.
