>I have a Campy record carbon seat post that slips in the frame. The frame is a new Mondonico Foco and has been faced/reamed. The inside of the seat tube is clean and measures 27.2. No grease has been added to either post or seat tube. Ive already broken a well greased Campy seatpost bolt. My local LBS said that I might need to switch posts. That sucks when you have a $100+ post that worked great in another frame. Any suggestions?Have you tried the frame with a "regular" aluminum post OR a different carbon seat post just to isolate the problem?
Is it possible that whoever faced & reamed the seat tube over did it?
If so, all is not lost -- BUT, you'll want to run the quick test with another seat post first.
If another 27.2 seatpost ALSO slips, then the problem is with the seat tube. Tsk. Tsk.
The fix will cost you about $5 and a minimal amount of time ... I'll spare you the details, for now.
