Carbon seat post?

I have a carbon post on my ti frame that started creaking. I tried cleaning it - no help... I had to get some friction paste to put on it. That cleared up the creaking right away. I'm glad that worked as it was going to drive me completely nuts...

Unfortunately it may not necessarily be your seat post. Clicking or creaking can be *a lot* of things. A pedal or a cleat might creak or click, a sticky link in the chain can cause a click you'll feel. A bottom bracket bearing can go bad and click, etc, etc, etc.
