If that's Gord Singleton's bike it would be, but that would be because of who rode it, not the bike itself. IN the 70's and 80's, most high end bikes were made from similar steels. Some brands made some funky designs with custom geometry or tubing. Moser made an interesting big wheel track bike for his hour record attempt. Colnago used to make double downtube bikes and bikes with square tubing, or even lobed tubing to emulate their company logo.
