Mondonico ID help?

I recently acquired a Mondonico off Craigslist. It had been poorly converted to a single speed. My plan is to do a full restoration but possibly with a modern Campagnolo group. Any Mondonico experts out there that might be able to identify which model an approximate age this frame is?

The vintage is 1984-1987, possibly 1988, assuming the Columbus decal is OEM. I don't know the model name for this period but my 1990 Torelli price list simply refers to it as Mondonico SLX. The 1991 list calls it the Mondonico Diamond.

No. I think TMar is pretty much on the button regarding identifying the frame itself, based on my older Mondonico and my recollection of the literature. I'm certainly not a Columbus expert.

I wonder if it's a repaint? The decals seem odd.

Here's a link that shows SLX and SPX were thicker with the helical ridges for professional cyclists and "SUPER BUTTED" It was heavier with SPX being for larger frames.

Thanks for the information. Iíll be taking it to a local shop that specializes in repairs, custom painting, and restorations. Looking forward to getting it back on the road.

Ok, so "Super Butted" refers to the helical "thickeners" on the butted sections. Thanks!

The five helical ridges in SLX. and SPX provide additional stiffness with only a nominal increase in weight. The concept had originally been used on the Columbus steerer tube. When Campagnolo's brazed-on front derailleur hanger appeared circa 1982, there was a rash of failures. The helical ridges were applied to the seat tube to add more material for brazing. Pro riders noticed a slight increase in bottom bracket stiffness and the concept was added to the bottom bracket ends of the down tube and chainstays to produce the SLX and SPX tubesets. TSX expanded on the concept by running the ridges the full length of the top and down tubes and reducing the butts to 0.8mm.
