I've been running one for a couple weeks or so. I have a bluto that likes to leak air, but the price was right, so I tried the Renegade. The fork has great clearance for width(lower legs are 6" apart), but I was disappointed to find that the Showshoe XXL does not clear the arch at the top. It will turn, but with much resistance. Dropping the pressure to sub 1 psi gets it close, but still some rub. I have to swap to my carbon fork for that tyre, which is a nuisance, but whatevs.
I found that the recommended pressure was way too low for my liking. It suggested 80 psi, I think, but I've been running it at 150. Might drop it down a hair. The rebound adjust works. It was a bit bouncy with minimum rebound setting. Dialed it up all the way and it went away. Ended up somewhere in the middle of the adjustment range. While I don't think the damping is anything special, it runs thru it's travel smoothly, holds air, and gets me some cushion on the fatbike. For the price paid, it's doing it's job. I didn't run them back to back, but believe it's stiffer than the bluto I ran before. The lockout works and is very firm. Almost rigid.
I don't regret it yet, but long term is the real test.
