The good people of 2Velo have a copy online of a 1987 Atala catalogue. Your bike looks like a variant of the 'Corsa GS' frame set.
Thanks for a great tip! The picture above also proves that green fits nicely.The paint doesn't look bad at all and the metallic green is a rather nice color, IMO. You could just replace the GIOS stickers with an Atala set and call it a day.

BTW, if your bike rides anywhere near as nicely as mine, you've got a pretty good deal.
The diameter seems to be less than 26.8The first thing to do would be to check the seatpost diameter, which will give an indication of the tubing used. Columbus would use a 26.8 or bigger size.
WRT the branding: if you found the bike in or near Germany or Austria it could also have been branded as a Gironelli. These were distributed by Neckermann, and were made by Rizzato. Also, there may be Maino bikes from that era with the same characteristics. Rizzato owned and used that name as well at the time.
Nope. I was wrong. The diameter is exactly 26.8The diameter seems to be less than 26.8
But I’m not sure if I’m measuring the proper place. Shouldn’t I measure the internal diameter of seatstay? It refers to the frame tubing vs seatpost which gives the value of the external element.
Sorry if this is a rookie question.
