However, given the extensive chrome, front derailleur hanger, internal brake cable routing, it would appear to be at least SL tubing and possibly SLX. Given, the dual bottle set-up and pump peg and graphics, I'd place it 1986-1987, possibly later if they had excess Columbus decal stock. The one curious item, is the presence of Gipiemme dropouts, which I don't recall seeing on a Benotto. Photo assist...
