Need help identifying this frame?
got it in trade for some wrenching. It has been debadged. All I know is that it was campy equipped. Italian? Steel vs Alum? It's surprisingly light.

It's definitely a Diamond Back (or at the fork is) and appears to be a circa 1990 Expert TG. It's Over sized, TIG welded, Tange steel of Tange #1 gauge. Originally Shimano RX100 equipped. There was also a 105SC equipped Master TG, which used the same frame but the marble effect was more gray than black. Serial number?
Edit: These are the bicycles that started the trend for TIG welded, steel, road bicycles. TIG welding was cheaper than developing proprietary lugs for the over sized tubes, which increased stiffness. These bicycles replaced Centurion's venerable Ironman series.

T-Mar to the rescue again! And I will opine that the band on the seat tube with Italian and World Champ stripes is from some Italian brand of handlebar tape, (so don't be fooled by that)

Thx T-Mar! Great info. Happy to know it's steel, as that's my preference. Not exactly my size but I recently made a 54cm fit with a long stem and it turned out really well, ergonomically. Like I said, surprisingly light and in nice condition, certainly good enough to build up. I like the look of it. I will look for that serial #.

I'm really surprised to see the serial number being from that early in 1989 but it does confirm a 1990 model, as 1990 was the first model year for Diamond Back road bicycles. If it was a 1989 Centurion, it would be lugged and use standard diameter tubing. I'm wondering if somebody inadvertently grabbed the wrong stamp for the 3rd character/month indicator?

Tange #1 is quite nice, and I really love the marble paint. Should be a nice bike (with white bar tape, of course).
It's a really cool sticker though!
