They were from the same owner, a regular De Rosa customer (a very wealthy customer), he knew Ugo and wanted two mountain bikes for his family, bikes that had never been used. I was told that the bikes were made to measure and that you could modify/change them (stickers, brakes etc) with Ugo, waiting times for this frame were very long because of the difficulty in welding these geometries. Another piece of information I was able to find, through the De Rosa family, is that the production of these bikes was very limited, maybe 4/5 pieces.
