I had the same seat post slippage problem with my 2018 Roadini. I phoned Rivendell, and the chap on the phone was not very helpful. I tried the carbon paste stuff; worked okay for a bit, but then the problem came back. In the end, I had Chris Kelly (framebuilder in Nevada City) put the seat post on his lathe and score a pattern into the post surface. This worked a treat-- with the scored pattern, the post stays put (it's not visible except when the seat post is out of the frame). He did charge me 25 dollars. Actually, I recall that Rivendell suggested scoring as a solution, but that was all. Any one with a metal lathe can easily fix this... but I do wish that Rivendell would address this problem more proactively. Cheers, Karl Weimar, CA.
