Corima seatpost slipping(2 posts)

I bought a Corima Ellipse carbon seatpost this winter, and I'm having trouble with the post allowing the seat to tilt back. I've tightened the post as tight as I can, but after every ride it tilts.

Would appreciate any suggestions. Thanks.

I tried a couple of things. First, lightly sand the carbon surface that faces the bolt adjustment. Then, lightly grease the tightening bolt and crank that puppy down. I had the same problem, so badly I was ready to toss the saddle until Corima suggested the above to me. Once I did those things, the saddle slippage stopped. I broke a bolt at one point, but Corima sent me a replacement (no charge). This was a few years ago - I finally got tired of the side to side sway of the post, and the slight forward and back rocking, and got rid of it entirely. I now ride a WR Compositi - lighter, more rigid, with a two bolt adjustment that's never been any problem at all.
