Quite often, I think mention already, the catalogues are made July-ish, ready for the Aug/Sept new model release.
I know often the new forks hadn't turned up, you'll often see last year's model on.
Similar for seat post etc than change a bit over the year.
The early Rocky mountain catalogues are riddled with it.
The 92 Altitude is full XT, last year's fork, wrong post iirc. When it came and is listed as having full XTR, which is quite a difference.
I think bomber forks when they released caused similar problems etc. 93 to 93 Rockshox similar.
So they can only photo what they have.
