Depends what you want it for I suppose, the Trance is a versatile bike, in stock form it’s a 140mm trail bike or the SX version comes with a 160mm fork and slacker HA.
I bought frame only about a year ago and have done both. Initially I used a 140mm Rev I had from a previous 45650b build, then I went to a 160mm X-Fusion to create my own SX version.
Both worked well, the 32mm Rev is not the flexy POS that a Fox-32 is….in fact it wasn’t that many years ago that the 150mm Rev was still making the Dirt-100, obviously it’s been superseded by a host of forks with 34mm, 35mm and 36mm stanchions but that doesn’t mean it became a bad fork overnight.
I now run mine on the front of my Ragley Piglet, it’s actually a great fork, I’d buy the bike and worry about a fork with longer/thicker stanchions later.
