Columbus is the maker of the tubing used to build the frame

Doesn't look exactly like that, but it did use Columbus tubing: 54cm SPECIALIZED Allez Elite Columbus Steel Carbon Road Bike ~5'7"-5'10" (bicycleczar.com)

Columbus had a steel frame Allez back in the early 00s. 04ish for sure. It was built with Columbus Foco tubing.

This red bike though? That's aluminum tubing. Columbus had aluminum tubing too, but I dont know why Specialized would use Columbus branded aluminum tubing over the generic tubing they used for so many other bikes.

The red bike looks like an Allez Pro from '07ish, but those didn't have 'Specialized' on the top tube and bottom tube. 'Allez Pro' was on the top tube.

Maybe the Columbus sticker was just added by an owner?

I live in Montreal. There are hundreds of Marinoni aluminum bikes around here built with Columbus aluminum tubesets. There have been a lot of bike builders who used Columbus aluminum tubing to build lightweight bike over the years. The OP's bike has carbon fiber seatstays which were probably made by Columbus

Marioni is a relatively small builder, even though it is a known brand in your area(and elsewhere too, kinda).
Brands that build in house with aluminum are pretty rare now and weren't exactly common in the early 00s.

Specialized uses aluminum tubing that is branded under their own system. A1 tubing, for example.
Maybe they paid Columbus some money 15 years ago for the privilege of a Columbus sticker. I know slx tubing, which is steel, was briefly used as a name for aluminum for some absurd reason.

Anyways, comparing the decisions of Marioni to that of Specialized is nuts. They are a totally different market.

Edited to add- Columbus E5 Aerotec tubing.

The carbon seat stays with Zertz inserts, and shaped seat tube smells a lot like a higher end frame from the early-mid 2000s. The K on the fork looks a lot like the Kestrel logo, which would make it non-original to the frame, but a quality item.
