anyone know when the GT stamped version came out?

Around 1990/1991 ish - think they ran until around 1994.

From memory I think it was around 1995/6 that the rounder sectioned 'Profile' stamped Profiles came out. Also worth noting that the 'Powerlite' stamped profiles came out the same time as the GT stamped ones - although these seemed to run for a lot longer - one of my mates bought a set of the Powerlite one's in 1997 and remember still seeing them in shops in 1998.

Quick edit - also the SS cranks came out 1998 - I got one of the first sets in the UK around September time I think, although the memory's a bit hazy  :D

91 to late 1999 as they were stock on the GT TOUR bike that legend Jamie bestwick rode  :4_17_5:

i was told that there was actually another set in between the second and third and that most people think they have seconds when they actually have thirds as the differance is tiny :-\

That'll be right , the Profile site info is limited  ;) .

Square box no indent - Gen1
Square box indent - Gen2
Slightly more rounded shape arm with indent - Gen3
Modern design even more rounded with no Profile writing & GT version .
Modern design with Profile writing .

Think that's roughly it , Gen 2 & 3 mixed up often .

(((sonic))):
2nd Gens.



3rd Gens



The 2nd Gens as stated above are a "box' crank with the much more common 3rd Gens much more rounded, the 2nds are chunky!
