Just a quick question. Sheldon Brown's database lists all Raleigh 3-speeds as having a 25.4 mm seat post diameter. I have a 1958 Sports and a 1975 DL-1 tourist for which I recently bought new 25.4 mm posts of extra length. They seem to be a tad small, though. Like, I can't visibly see any sort of gap when I insert the post, but I notice that I have to tighten the bolt by a few extra turns. When I had a quick release on the Sports, the old seat post was no trouble but with the new one, I really had to crank it down.
Is it safe to assume a 26.0 mm post will be a better fit? Also, if I find that the seat tube has been squeezed together to the point that it will no longer return to its original diameter, what is a good way to push the clamp area back out?
Edit: or is it possible that the new posts were wrong size or badly manufactured. I don't have a caliper to confirm any of this so if anybody happens to know the diameter of their 3-speed's seat post, that would be a great help.
