I’ve gone back and forth between hardtails and full sus over the years. I don’t think I could justify more than one MTB at a time.
Earlier this year, I dipped my toe into the full sus waters again with a second hand Transition Scout frame and swapped over the parts from my old Soul. I didn’t set out to buy a used one, but it made the changeover a lot cheaper / lower risk than getting a £1,500+ new frame.
It’s been great to try something different, but I think the newer frame’s geometry and dropper may have made as much impact as the rear bounce. It’s not that the suspension isn’t lovely, but there are other things that are good about it that could be good on another hardtail.
I’ve got a custom road frame coming soon and could certainly see myself with something like the BTR in future. I’d add that the market for a used custom frame is likely to be limited.
