For 2019 CTR I ran a FS Kona Hei Hei 140mm travel bike with Remote lockout shock, and a dropper post with a seat pack. No issues with any of it, performed flawlessly. My only mechanical issue was a broken spoke. If you go into it with a fresh service on your fork/shocks and a mechanical dropper like a 9point8 fall line I don't think the risk is really that big. For me it's the only way I would do that trail, but I'm not a hardtail guy unless it's flow trail. (which CTR is not). I have a lot of respect for hardtail riders though!
