No it doesn't, however there are many mounting kit options. I bought an axiom fatliner that is made for fat bikes and was a perfect fit. I used Portland design mounting brackets...they weren't wide enough to boy through but wrapped tightly enough that I'm using them for the time being.

I'm not sure that one you linked will work. Is it fat bike specific? Fat bikes have much wider drop outs than normal bikes. Also, with disc brakes the mount needs to wrap from behind. The axiom wrapped around the brakes and is built specifically for fat, I'd recommend!
