Hi all,
this is my first post on this forum.
As I also have a MS tube frame I was thinking it's a good thing to contribute to the story. Here is my MAZA Elite in Columbus MS tubing. From my research on the builder and the era, I think it was made in 89-90's. Mine is fitted with complete DA 7400 8 speed groupset. So almost period correct.
Here:
http://cicli-berlinetta.de/2015/10/23/m ... pe-tubing/ is a link to a different MAZA from the same era (my frame has the serial number is 13, the Cicli Berlinetta one is 10).
One more thing, as far as I know the seat tube diameter is 25mm not 25.4mm.
Best, Stefan
