I actually have one of these forks (or at least it looks the same). I bought it from elita one a few years back on sale. The quality of the fork was half decent.
My issues where: the post mount for the brake was not compleated flat (needed to be faced), the through axle was super heavy, and the fork had somewhat limited tire clearance (2.3 if I remember).
The 480mm should be fine since the 26mm is supposed to correct for the sag of the fork.
