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?
