My slide caliper sucks and doesn't measure fractions of a MM. I knew I needed a 26.something for my Peugeot build and went to Sheldon's seat post database to hopefully make an educated guesstimate on the size I need.
Anyways, I bought a 26.4. When I slide it in it is kinda difficult to get it in initially then it slides right in after the first 2 inches or so. The ears on the seat lug aren't crimped in at all but when the post is fully inserted I can move it back and forth ever so slightly. Is that an issue?
I think it will tighten just fine (I need a binder bolt) but again it will move the slightest lil bit way down in the tube. What say you? I've seen shims that only extended 2 inches into the frame so am I just being paranoid? Or should I pick up a 26.6? I don't like shims......Oh and it's supposedly 531 which makes me think it's just thinner further down the tube and therefore natural that a post could move a bit down in there.

Thanks,
