Is the frame brand new?
If that's the case, did you condition the seatpost clamp first? When I bought my tr727 straight from leader via coghouse it came with paper instructions on how to condition the seatpost clamp. You have to tighten and loosen the seatpost clamp 5 - 6 times before mounting a seatpost properly without slipping. Very important considering the seatpost clamp is integrated and too much torque can strip it/ your frame. If you already did that; try doing it a couple more times, but a tad bit tighter.

Now it has some raspyness to it and it grabs onto the frame better.
This lacked judgement.
