Dyna Beads how's it going !!!

[roboto65]

Ok so wanted to know how the Dynabeads are doing I figure it one of those things you forget about butttttttttt I wanted to see if you would buy again? Was the cost too much and would you buy them if they were cheaper?

Since we need 2oz for the front and 3oz for the back kinda easy just wanted to get an Idea of how it is going !!!!

I am going somewhere with this !!!!

[hootmon]

It's going great as far as I can tell..
Won't know for sure until I take the Car tire off, and it looks like that is going to be a while yet..
I have over 10K and the tire is still very much in balance...

I will purchase more in the future, but I also don't see why the product would not be reusable..
Take the tire off, reclaim the beads, clean them off some with a good degreaser, and reinsert in a new tire.. So if you can use them in more than one tire over time, does that make the cost more reasonable???

I'm a tad bit confused here . I was under the impression only 1oz. was needed for the front and 2oz's for the rear.

Well ya see when some of them went Darkside thus the 3oz forgot about the front 1oz sounds good to me !!!

It'd be a little cheaper anyhow.

I haven't had mine long enough to give any type of lifetime reading.  I bought 3 oz for like $6, but it cost me $7 to have them shipped!!

Well lets just say I can get you the beads for 1.50 an oz you in ???    Who is ordering LOL

Being a naturally curious person, I wondered if maybe bird shot would work as well.  So this afternoon, I disemboweled a couple of shotgun shells and relieved them of their #8 lead shot.

I tried the famous "spinning bottle" experiment.  Took a plastic pop bottle, drilled the lid dead center, put a bolt through the lid, chucked it up and turned it in a hand drill.  As I expected, it spun true.  I then weighed a small bolt from the spare bolt pile, and the two shells' fill of shot.  The shot weighed like 3x the bolt.  

Taped the bolt to the outside of the bottle, and sure enough, it was severely unbalanced.  Poured the shot in the bottle, and it had a negative effect, if any at all.  Took the bolt off the outside of the bottle.  The bottle spun true, with the shot rolling harmlessly in the lowest surface of the bottle.

So then I decided to try the rest of the dynabeads, as a check.  Dumped out the shot, inserted the dynabeads, and behold!  They made the unbalance worse!  They generate a lot of static electricity and stick to the side of anything plastic that contains them, including the squeeze dispenser bottle I filched from the wife's kitchen where I store them.  They tend to distribute themselves around the circumference of the inside of the bottle.

So then I removed the bolt, and the beads, retested the bottle empty to see if it still ran true, put the beads back in the bottle, and it quickly became unstable, with no unbalancing weight at all.

Now I am wishing I had tried the new tires by riding them before I put dynabeads in the rear (car) tire.  As stated before, the bike runs super-smooth.  Smoother than any I have ever ridden.

So now I am totally confused.  I have read conflicting opinions on boards about the effectiveness of this product, and I don't know what to think.  

Have any of you run the test in the correct order?  Pump up and ride the tire, then insert the beads and compare the results?

The best I can do is say that the Magna I put the car tire on had about 2 oz on the rim to balance it I put the beads in and removed the lead and had no problems with balance at all.  Now what kinda bottle did you use because profile has a lot to do with it to the beads will not work in a wide tire.

[roboto65]

Also the static is normal

When you come to a stop, do the beads fall to the bottom of the tire?
Yes. Due to a small static charge built up between the bead and rubber interaction, a few will remain attached to the tire circumference, but only a very small amount. The rest fall to the bottom and reposition themselves when the tire starts rolling again.

OK, I did use an 8 oz Diet Dr. Pepper bottle -- it is "wider" (in the test sense) than it is "tall".  These are with the bottle laying down, so the normal "height" is actually the "width" as it simulates a tire.  

The demo I saw used a quart or 1/2 gallon bottle, which will have a different ratio, but is still "wider" than it is "tall".  

Hmmm.  Maybe I will look for another test container that better simulates a tire's shape.  I would still like to know if the beads have to be ceramic, or if lead or steel would also work (and be a lot cheaper!)

My assumption is that the electrostatic attraction (to the bottle) and repulsion (from other beads) is not key to their operation.  Or is it??

I have aquestion about installing the beads, several suggestion on filling thru the valve stem have been offered. My question is, can the beads be added while the tire is being mounted, that is assuming your replacing the tire anyway?

[roboto65]

Yeah that is the best time to do it

Taped the bolt to the outside of the bottle, and sure enough, it was severely unbalanced.  Poured the shot in the bottle, and it had a negative effect, if any at all.  Took the bolt off the outside of the bottle.  The bottle spun true, with the shot rolling harmlessly in the lowest surface of the bottle.

What you are saying here is the shot had no effect, correct? What if the bolt were a bit lighter than the shot? What you put into a tire may only handle a certain percentage of the off balance weight.
