Back to the orig topic with a an amendment. Perhaps my orig. "1mm" claim was too high. I would now estimate that it is closer to 0.5mm-0.3mm.
Reason being: I found the orig Fuji OEM seatpost (that I replaced the Satori with in the Fujil it installed w/o incident) . And the OEM has the same no-fit issue -- on vintage GF and Schwinn -- as the Satori. A nat's gluteus hair too wide.
My orig speculation was that ID and OD specs have changed or became ad hoc. I'm more convinced of this now.

BTW: What a weird decision it was to close the other thread. And all the supporting "likes" to the mod decision -- the very definition of filter bubbleness and echo chambers . Immature and cowardly. Restaurant kitchens run hot, folks, and temperaments are on the menu. But scrumptiousness of the cuisine is the ultimate end product. It keeps the critics comin' back for review blurbs. "If you can't stand the heat...."
