A cure for creaky carbon - seatpost I think
I have a (nearly) new Wilier Mortirolo and the seatpost creaks - it's a Ritchey Pro carbon and the frame is carbon. Before I go to the bike shop and get sold something I don't really need, is there anything I can use to stop it?

First, is the creak in the seatpost/frame inteface or in the saddle rail/saddle clamp joint? There is a product called "Carbon Assembly Paste" that is recommended for carbon components in place of grease. It provides a non-slip function and keeps the seatpost from freezing in the frame too. So, the shop will sell you something you really do need.

+1 I also think you might be looking at a seat/clamp problem. I have a B67 that creaks, no matter what seatpost I use it on, so that may be a consideration too.

LBS cleaned and lubed the seatpost for free, but it's still creaking... or rather, the bike is still creaking. No creaking if I stand, or if I sit on the top tube (awkward, but it had to be done), so I guess it MUST be the saddle or tube. I'll get some lube and try to figure it out myself, otherwise it's a strip-down job.

+2 I had this problem, went the "Carbon Assembly Paste" route with no effect...then dis-assembled, lubed and re-tightened my saddle clamp and the squeak stopped.

My "S-Works" carbon seatpost clamp was the culprit when I was diagnosing my click/creak issue on my Tarmac. Try doing what dstrong suggested to see if it helps.
In my case a badly designed seat post is where the problem originated from. A Thompson post fixed everything.

Lets confirm that the OP is 100% sure and has taken the steps necessary to ensure that actually is the seatpost/seat area that is causing noise?

The only firm evidence is that the creak stops when he stands or puts his weight on the toptube so that does point to the saddle/seatpost as the culprit.

Took off the saddle, cleaned the clamp, lubed and tightened it up. Things improved, but it's still creaking a little. I think it's the non-incremental saddle clamp, which is not that great a fit to the post - it kind of sits against the post on it's four corners. Most other clamps I've has have been incremental - I think... (certainly the Thomson's on my mtb's) or I've not noticed because they didn't creak. I'll probably live with it for a month or two and see if it 'beds in' at all.
