Can anyone ID this shell?

1. That is not a 3Rensho product. It's not even Japanese.

2. It's definitely Italian built. Mid-size factory; not an
artisan builder, not Bianchi etc.

3. I do not know. It is the same shell Basso used at one
time. Could possibly be a Basso but I do not know that.
Either he measured poorly or it's not a Basso as the
geometry as listed makes no sense:

Mid 1990s Gap used that shell, after the one with the panto
"B" logo was dropped.
I don't have an upside-down Basso snapshot and a web search
was fruitless.

Here's the matching shell on a 1990 Basso Gap. Other details
differ, though: brake bridge, seat cluster, etc.

Thanks so much; I gave up the search after 10 minutes.
That's a Basso Gap Mexico.


Did they have the Olympics in Mexico in 1990? Colnago has a Super Mexico as well if memory serves.


It's a color series with (AFAIK) no particular deeper
meaning. Started with Black-Yellow-Green Basso Jamaica which
was popular and followed promptly by RWB Basso America then
Blue-on-Blue Europa, Raspberry-Silver Canada, Pink-Green
Mexico. (oddly, no Tricolore Italia)

p.s. Summer Olympics cities- 1988 Seoul 1992 Barcelona.
p.p.s. Merckx set the Hour in 1972 at Mexico on a Molteni
Orange Colnago with Merckx graphics.
