I might have to get back to you on that one, I've barely had a chance to ride it, so it's hard to say how it feels.
I also can't really make a comparison between this and newer 24s, because I've genuinely never ridden a 24 before, which will probably make people rage! ha.
From initial impressions, it feels surprisingly modern. The longer chainstays are probably the most old-school feature. I had a much lower and even shorter front end set-up on it a few weeks ago, it felt ok for most things but not bunnyhops, which is exactly what I wanted to be doing!
Maybe you're right about short high stems not really existing at that time, or maybe they had silly long forks back then, I dunno.
Some rough 'tape measure' geo:
1035, +30, 385
That's with the justice forks.
