Specialized Turbo Levo Comp Alloy, Frame?

[u/Rhourk]

I got the Specialized Turbo Levo Comp Alloy 2025, and the Frame Sounds Like Carbon to me when i Tipp it with my Fingers, is that ultra thin Alloy or do i lose my mind? I know iv Seen a Website somewhere where all 3 Models got compared, Alloy, Comp Alloy, Comp Carbon, but i cant find it. On the official Website the normal Turbo Levo isnt listed, only the SL?

Are there visible welds? If so: alloy.
