I've been meaning to ask this about other member's upper tier late 80s schwinn road bikes, but keep forgetting.
I have an 87 prelude and an 88 premis, both tenax, and the seat tube is quite literally slammed and squished into the bottom bracket shell to fit with the down tube(vs being mitered/coped to fit inside the shell with joining tubes).
Any chance you happened to look at the joining method of your Prologue? I know the Prologue is Panasonic built with Prestige tubing, vs Greenville built with Tenax tubing like the rest of the upper tier of bikes, but just curious if the slam and squish build method was used for the highest level bikes too(with Prestige or SL tubing).
