what is that noise inside my nomad ????

bit of a long shot here guys but im hoping its something or nothing, just checked my nomad as you do… and it sounds like theres a stone inside the frame or a small nut? ive took my shock off and fork and wheels to make sure its defo inside the frame and shook the frame and the sounds coming from the bottom area near the BB, i took this out and still not coming out, theres no holes in the frame to escape from tbh, the only thing i could try is take the seatpost off but last time i did this i snapped the cable lol, has anyone had this problem before? ive no idea how its got in or what it is.. ive looked all over for any missing bolts and theres nothing missing at all from the bike, what u guys rekon? hopefully tomorrow i might be able to ride it free lol, the only thing i can suggest is something from my levi cable post dropper has come out the bottom and fallen into the frame but it still works totally fine? i dont really want to take it out again incase it breaks lol, what u guys rekon anyway?

Internally routed cables/hoses knocking about a bit?

no its not that cause it makes the noise on tilting lol

The carbon nomad has full length internal tubes for the cables. Maybes one has snapped or a bit chipped off one?

ah right perhaps? il have to take the seatpost off to see if it will come out cause theres no otherway it can get out?

If it’s an alloy Nomad I had a similar thing.
A stone had got into the chainstay via a breather hole near the rear axle.
Rattled up and down the inside of the tube in a real annoying manner.
