Bought this complete 1995 Rocky Mountain Equipe for a little more than a song. Been tuning it up and have done a couple of upgrades. I've had it for a couple weeks now and noticed today there's an ever so slight change in the outside diameter of the seattube a couple of inches below the top tube. The diameter change seems the same all away around (no calipers to check unfortunately).
Some notes:
1) The catalog (confident I got the year right) says 26.8mm seattube/post
2) Came with a super greased up 26.8mm seat post thats been slipping without tightening the clamp pretty hard.
3) I couldn't help myself and have taken it down some pretty chunky trails this week 😝
My thoughts are:
1) Tubes came like that
2) someone at some point tired real hard to smash in a 27.2mm or something into it at some point.
3) A very semeteric "ovaling" has occured.
Seems like the bike has had very little use. With zero force i tried a 27.2mm post and it didn't fit at all (maybe the clamp has made the opening 26.8mm?). All in all, I love this frame so far and have been really enjoying it. I'd love to put a bit of love and upgrades into it but don't want to if the frame is compromised. Is it something to worry about?
Thank you for your time. I'm a bike newb and I really appreciate anything anyone has to offer 🙂

27.0 maybe? but probably 26.8
Seattubes are often externally butted, I’ve had a couple frames built with tubing like that.
26.8 is standard for Rockies of that era.
Is it a cam quick release? If you clean and lube the cam, it’ll work 200% better.
Its just an externally butted seat tube.
