Hi Ron,
In the video, going left is faster than going right. The tires are about the
same pressure, although it seems that the 20" is software, probably because it
takes more hit. Some instance you can see that the rear 24" takes more hit
then then front, at slower speed.
The 20" feels rougher, but I can't feel any difference in steering disturbance
vs. the 24". Will need compare random bumps on the trail...

Hi Vi,
Can you give us a reaction, maybe also on the python list of what your
subjective feeling was while riding the different bikes? Great vids in general
from you by the way!
regards,
Ron Hongsermeier
