I'm not at home today to check but there is a ceramic brand of beads that work differently than the Dyna Beads. Somehow (PFM) after the beads settle in the tire thay stay attached to the rubber instead off falling to the bottom of the wheel every time you stop. Could be a static charge that does it, not sure. I will look at them when I get home. I picked them up at a bike show at a booth across from the Dyna Beads booth.
I'd be willing to pitch in for the bucket of beads, what ever the brand. I have been very happy with the results.
