I am interested to know your thoughts. I think the frame was originally red and was chromed later. It is in columbus tubing and lacks a frame number. There are no dents or bends. The seat tube is 54cm centre-to-centre and this is stamped onto the seat cluster, which takes a 27.2mm-diameter seat post. There are a total of 8 heart cutouts in the pressed lugs. The seatstay caps are scalloped. The pressed bottom bracket is Italian in diameter and threading and, whilst it has no heart cutouts, it does have two simple cutouts either side of the join. I believe that the short rear dropout is Campagnolo but the name has been ground out of it. It has a slope-topped investment cast fork crown. All of these things make me think that it is a De Rosa. However, there are no fork blade stiffeners and there are no diamond-shaped anchor points for the rear brake bridge or the chainstay bridge. Furthermore, I have no idea why there should be three stars in the fork crowns and seatstay caps. Any ideas?

I thought the hallmark of any De Rosa was the diamond-shaped chainstays? Doesn't look like that one has 'em, and my early 80's De Rosa had "De Rosa" engraved in the seatstay caps. My guess is no.

I doubt it is a De Rosa. Nice frame though.

Why do you think it is a De Rosa?

It doesn't look like any De Rosa I've come across - and I can't imagine them putting a 54 into the seatstay cap. Not to be rude, but that looks a lot cruder than De Rosa to me - especially the brake bridge and chunky lugs.

There's nothing that points to it being a DeRosa. The heart shaped cutouts in the lugs aren't hearts, not even really sure why people think they look like hearts, and they've been used on a zillion different manufacturer's frames. Also, if those are Campagnolo dropouts, they've been reworked quite a bit. Not to mention, why would anyone grind the name off?

No idea what it is, but it isn't a DeRosa, that's for sure.

Not a De Rosa.

It was chromed, then painted. At some point the paint was removed.

Getting a Japanese copy of an Italian frame vibe. Lugwork and seamed BB shell point to this. I would guess late 70's early '80's on year. OP are you in Austrailia? Weighing the frame would probably be the best indicator of quality. Agree with the chromed, painted, stripped scenario.

it's probably a confente, just kidding.... unfortunately that doesn't scream de rosa or anything. It's a nice frame just not a de rosa.

Thanks folks, that's very helpful.
