Reynolds introduced 501 for the 1983 model year, but we know based on the extant catalogue that Batayus wasn't using it that year. I don't have any literature for the 1984 Criterium but it was spec'd...

Ishiwata steerer tubes will typically be stamped. Early versions used their logo, which looks like two concentric circles with an "I.S" at the bottom. The two concentric circles represent the cross...

Ishiwata 025 was a mixed tubeset, using the double butted down tube from Ishiwata 022 with plain gauge CrMo elsewhere. The plain gauge seat tube used on Ishiwata 025 typically employed a 26.8mm seat...

27.2mm is consistent with Ishiwata 022. I'm not aware of any plain gauge CrMo sets that would have used this large a post during this era. Still, I find it very strange that they didn't exploit...

I wouldn't assume this was Ishiwata 022. Marketing people typically wouldn't miss the opportunity to mention "butted" on the tubing decal. I suspect it's plain gauge CrMo. The seat post size may...
