Gios Evolution is indeed a later frame, but Barry's not saying it isn't - this is a homage to, not a reconstruction of the original team bikes.
Perhaps the thread title "Gios Brooklyn replica" needs to be changed.
Original Brooklyn bike was with the graphics Barry's using. Evolution looks to be pretty much identical frame bar the Gios engraving in the BB shell - and probably lighter tubes and wider rear hub spacing. Recessed brake bolts are also a modern feature.
Also different fork crown, top eyes, cable routing, probably different lugs and braze ons, so not really "pretty much identical frame".
It would be the equivalent of taking a late 1980s/1990s Raleigh frame and refinishing it in the red, yellow and black TI Raleigh colours and graphics.
