Other than that, the larger sized 20 is so close to a size S with the exception of longer toptube on the cannondale because frame size was meant for bigger people and taller standover on the canyon because bigger wheels.
My conclusion? 90s rigid is pretty much a gravel bike except the sizes and geometry is shifted a bit because wheel size.
