  1. Looks like the wedge piece is missing and the screw is in direct contact with the seatpost. Check the front end of the seatpost for damage (which I highly suggest when only the bolt secured the post and it was slipping)

  2. Yeah, my ultimate has the same problem, and the seat kept sliding, even though you tighten the screw. So I put a little Loctite on the wedge and lots of carbon paste. And now it doesn’t move.

    The screw post goes that far on my grail. I say your fine if you applied carbon paste and torqued properly.
