I did do a bit of reading ala google. And mcn reviewed em, said they didn't do anything.
Some ppl say they cause severe imbalance at high speeds.
Then I happen upon an idea that put it to rest for me. How come the only proof they have is a water bottle and a drill? Where is the documentation? The racers who use them? The scientific documentation?
Of the several threads I've read on different forums they all say the same, "they make no sense".
And then somebody posted a dynabeads FAQ which stated they would not work on "race" tires because the rubber is too soft.
