Looking good. Endless sandy jeep/moto trails where I live. I want (no need!) a fatbike. Love the black and yellow look of the first bike.

So… used with a suspension fork, would the rack/cargo become unsprung weight?

@Dillao – yep, as long as the stabilizer bars are mounted to the fork lowers it is unsprung mass
