The Ishiwata EX (Exactus) tubeset is based on the revered 022 but is triple butted, having slightly thinner butts at the head tube end of the top and down tubes. As a result, it is actually slightly lighter than 022, though there was also a version using with heavier gauge Magny (carbon-manganese) stays and forks. Unlike 022, it used seamed construction, allowing a lower price level.

The one thing that strikes me as odd are the rims. I realize that wider tyres have been fitted, but still the rims look wider than what I recall seeing on this model.
