Once I decided, to permanently ride a Thomson Masterpiece, I used carbon paste (based on some possibly dubious advice) as I sensed there was some slipping. At some point, the bike developed an intermittent creak, mostly when climbing (saddle or out). I stripped the bike and creak remained. Became convinced there was a crack but had it ruled out by the dealer. Sold the frame, bought a new Moots. Creak returned. Only after a few weeks did I realize I was using the same Thomson post and I hadn't wiped it down. Cleaned the post; creak disappeared.
Recently a pal's RSL was creaking up a storm. His wrench was convinced that his White Industries crank wasn't properly installed (you know, that goofy M30). They went through that whole song and dance. Finally, he listened to me and removed the post. His wrench reluctantly lubed it with anti-seize (had grease in there previously); creak disappeared.
Short story long, with a Ti frame it's always the quick release.
Thanks for the information!
