Probably upgraded to a full suspension bike and didn't see any reason to keep the hardtail around. I just sold an even nicer hardtail for $700. It was a mix of parts from my cracked full suspension bike and new parts. On-One Parkwood frame 1x11 XT drivetrain, carbon crank, dropper post, fox fork, slx brakes, quality American Classic wheels, blah blah $700. I sold it because I just bought a new full suspension bike, have a rigid, and yet another hardtail that I also need to sell and is equally well equip and will shoot for $700 for it too.
