Hi Everyone,
I recently acquired a 1989/90 non-export, Japan-only frameset with a tubing sticker stating only, "Bridgestone/ Cro-Mo frame." According to B'Stone's catalog for that year, frame & fork are indeed full Cro-Mo, but offers no further details; I'm kinda curious to know what it was.
Earlier models of this particular frame were made with Ishiwata triple & quad-butted tubesets and, while the frame is reasonably light, I can't imagine it's tri-butted. That said, the interior of the ST seems to measure 26.8 & the outside measurement is about 28.6. Any insights?
