Not quite.

Tretubi was a lower-grade combination of Columbus tubing that consisted of SL or SP in the main triangle and unnamed seamed or seamless chromium-molybdenum or high-tensile steel in the forks and stays.

Nothing wrong with it, of course---my favorite among all my bikes was an '82 Bianchi Eco Pista built with columbus Aelle (a.k.a. high-tensile steel) throughout. Stolen 10 years ago. I miss that bike.

Also, butted forks and stays are generally single butted, not double butted.

And you survived. They didn't call that the death fork for nothing.

Actually, I bought the bike new, and that was what the manufacturer advertised and lbs told me: sl in the three diamond tubes, and sp in the forks and stays.
