Message: >>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. > If you want to use the post, you can use the old aluminum beer can shim trick. Just take an aluminum can, cut out a section to wrap around the post without overlapping, insert into frame. If there is too much shim, just reduce its length until it works. A tried and true method. Also works great for crown races that have an i.d. slightly larger than the crown race seat o.d. I think the thickness of the aluminum can is approx .1mm.
