I read horror stories that it can crack your frame if you install it incorrectly, but i don’t really see why it would do that because it doesn’t look like you can do anything wrong? Or am i missing something
I’m a light rider (~60kg) if that matters

Ye no problemo. It’s what it’s made for👍
Get a new dropper. 34.9 is better and spacers/adapters like that cause excess stress on the dropper and the frame.
I’ve run this exact one for the past year with no problems
Sure, that will work but it’s also another spot that will eventually creak and the shim could get stuck in the new frame. If it were me, I’d keep the old dropper with the old frame and buy a new dropper with the new frame.
It’s absolutely fine, and will never give you any trouble as long as the shim is the correct size. Think about it this way:
The frame won’t know that it’s squeezing a shim instead of a seatpost.
The seatpost won’t know that it’s being squeezed by a shim instead of a frame.
It depends. I’ve used a few now without any issues whatsoever- but if you’re already heavily invested in a new frame AND intend to use it for a long time, it’d be smarter to get a new dropper. Maybe use the shim temporarily?
Either way, search for the longest shim you can. Some are short, and that places lots of stress on the frame.
I’ve used a 31.6mm Reverb AXS with that exact shim for 3 years now no problems. And no, you won’t crack your frame. Just install the opening on the same side it’s on your frame (even that doesn’t make much of a difference) and make sure it’s inserted all the way to the collar.
I have to use this in one of my frames because they don’t make a dropper in 28.6. I used carbon paste to make sure it was secure and torqued it down to spec. No issues so far.
The bike was second hand and actually came with a cheap AE shim and the original seat post would slip. I swapped it for the cane creek one and now there’s no issue.
The post will flex inside the frame. You would have to get a shim that’s long enough to completely pass the bottom of the top tube. Still IMO it’s a bit of a risk.
Shims are OK as long as they are the proper size and fit. Check on them periodically and it doesn’t hurt to remove, clean, and lube to prevent seizing and creaking especially if you ride in extreme conditions.
