yeah, it's a coupla inches in each direction. old style cantilever forks (the bent forward schwinn style) are the most noticable. i don't think the designer back then knew it, but he made the first shockless, springless suspension fork. this design was used on racing bikes as a way to make up for lousy road conditions, and is still in use today.
my '56 goodyear has those style of forks, and they shimmy forward and back like crazy at speed.
my last bike had american made, heavy steel, tubular forks, and they rocked back and forth even worse, because of their ridgid design.
if you don't believe me, take a look at your fork the next time your jamming down the street. especially on a road with a few bumps in it.
most companies aren't gonna even try to explain that their bikes have "suspensionless suspension," but they all do, whether it was done purposely, or not.
