I've got a '98 YBB that I built up from a purchased frame. I cheaped out on the seatpost and got a generic post and quick-release clamp in size 27.2mm. It's all but impossible to get it tight enough, so I'm wondering if I just need a "better" post in size 27.2 or do I need a 27.3, which I see is sporadically available?
I haven't yet tried the "chalk trick". I will try that next, but I'm not terribly optimistic.
