Little wiggle of the saddle on Bianchi Oltre XR2

Hello everyone.
I have this Bianchi Oltre XR2. I'm not sure if this has been around from the beginning to be honest but I've noticed that if I try to push the saddlepost forward, there is a small "wiggle".
Now, the saddlepost does not move neither up nor down so I guess the clamp is actually camping.
I wonder if this very very little wiggle is acceptable or I'm risking my life by riding it on road (currently on the turbo trainer).
I've tried to upload a video. wasnt easy to move the saddlepost and keep the phone steady. if you look carefully you'll see it wiggle. Thanks

Take the seatpost out, clean it, clean the seat tube. check them for any damage. If not, apply lots of fresh carbon grip paste, put it back in and use a torque wrench to tighten the clamp properly to 5nm. Let us know how you get on.

Your seatpost is also set very high. Check where the minimum insertion line is on the seatpost, there may not be enough seatpost left below the clamp for a secure fit, the bike may be too small for you if so.

I've lowered the seatpost since (but I was far above the minumum line).
The whole area has been cleaned and carbon paste regreased already. Obviously torqued to 5Nm. I should have mentioned this probably.

It looks to me, that with or without the clam, the wiggle is the same. Only difference is that the saddle does not move up/down with the clamp clamped

Weren’t the Canyon Aeroad seat posts behaving similarly? And that ended up in Canyon developing a “solution”* because the movement was damaging the frame.

Have you checked, does your frame look okay?

I couldn’t open the video - how much movement?

*it didn’t really work

It Is really small wiggle though. The frame does not look damaged to me.
On my other bike, carbon seatpost and alu frame, there is no movement at all. I'm not entirely sure if a little movement is expected

I sent the pictures and the video to a carbon frame repair specialist and it looks like I may have a problem here....

"The clamp insert has debonded and/ or cracked inside the seat tube. We have repaired these in the passed by as a design these do fail from time to time so we cannot guarantee the life span of this although the repair is the same as an original bond maybe slightly stronger."

I guess it is time for some repairs. Sadly I will have to strip all the components:(
