Think by designation "Trail" is something in the 120/130mm travel segment. XC is usually 100mm and All Mountain is 150mm and up. A bike like the Pivot Mach 4 or Specialized Camber would be considered trail.
By the looks the Revolver is an XC bike. A Trail hardtail would have somewhere between 120 and 140mm of travel. Like a Kona Honzo, Niner ROS 9, or any of the Canfield HT's.
The Revolver 9.3 looks pretty legit...especially at under 2k.

Looking at the pic of the 9.3. It comes with X1...but the specs say Deore. Whats up with that?
