Thank you very much!
In this photo, the saddle rails are in the middle of the clamps.
And I can not move the saddle much forward. The reason is this.
The reason why I intend to sell my Simplon Nexio is not only the impossibility (as I think) of sitting right position, but also that the saddle slides in the seatpost. Exactly the same problem exists in Cervelo S5:

That's why I can not move the saddle much forward, because this will change the position of the saddle at the pressure of my weight...
I cleaned the clamping surface and the rails from the dust on my Specialized Phenom , also cleared the clamping hole of seatpost pin and put the Finish Line Fiber Grip Carbon inside the seatpost clamping hole. The effect was, but it was short-lived, and still on the next pit I collapsed down with the saddle.
I understand that I just need to move the saddle forward, but I can not do it for the reason indicated above.
Honestly, when I bought this bike, I did not think that its geometry would be SO different from the endurance geometry. I bought it a year ago, and rode not so much, constantly being in search of the best position on the bike.
I bought this bike in the hope that it will be with me as long as possible, but it seems I was wrong ...
If I purposefully want to change the bike, can I go with ETT 540-545?
