carbon on carbon seat post slip

Ive tried it all and still it slips a little.Im at the point where i just accept the fact that a carbon seat post is gonna slip on a carbon frame.LBS is useless.I could bore you with all i have tried but why put you guys through it.This is my last shot.

Have you tried friction paste made for carbon to carbon fittings? It's gritty and works well for me.

I assume you've already tried a paste or gel, but I'll mention what I use when I mount my aerobars to my carbon handlebars: http://www.amazon.com/Finish-Line-Bi...1601081&sr=8-4

Without it, they'll end up slipping every once in a while.

This maybe a long-shot but this is what happened to my carbon on carbon, the clamp bottomed out. Had to file each side a little to get more clamping force around the tube. This fixed my issues once I applied paste, sanded the inside of tube and post to roughen up and applied proper torque (5 on mine).

+1 on the paste, plus I had to get a new clamp as the old one seemed to not have enough grip

"First of all, carbon frames generally have a separate band clamp to tighten the seatpost, and, yes, the worst that can happen, assuming you are using the right size seatpost in it, is that you will strip the threads in the clamp and have to replace it. "

I don't worry about it so much anymore.

We're on an internet forum, so we're already bored. Why don't you tell us everything you've tried. If the above (excellent) suggestions don't work, you can always get a butane torch and weld the post into the frame. Plastic's melting point is only about 420 degrees. Might make it brittle, but if you've already tried everything and your LBS is useless...
