Anybody ever use this stuff?

[dpep]

Supposed to balance your wheels without weights. The only other product I know of that claims to do that is Slime, but it makes al mess on your rim.

mmmm I'm not convinced that this will address wheel imbalance.
I would expect this stuff to distribute itself around the wheel proportional to the distance from the centre of rotation.
Centrifugal force.
There may be some perceived benefit (smoothness) due to the increased flywheel effect. (but that would make it harder to tip into corners)
Plus increasing mass overall would make any inherent imbalance a smaller percentage of the total weight.
So on that basis it would help.
mmm Just contradicted myself.
But that's different to a correctly balanced wheel.

My bad. I thought it was something new just because it was to me.

No prob, I hope I didn't seem like a smart arse then.

Nope. Only dutiful.

I had never heard of it either.
A bit of research shows it to a bit controversial.

I haven't used them on my GS but I did use them on a couple of 150CC scooters though. I did notice a difference in the ride when using them. I installed them throught the valve stem with the tire on the bike. Putting them in this way took a little time but I would say the results are worth it.

I purchased mine through a bike shop in KC that primarily dealt in sport bikes. I spoke to the owner because I was skeptical at first. He showed me 2-3 bikes he owned that had them in the tires, 2 R1's and a Duck. He was pleased with the results and none of those bikes had any sort of stick on weights. The duck was used as a track bike.

I haven't used them on the GS because the tires I purchased came with balancing as part of the price.

As far as changing a tire with them installed, I doubt they would be any trouble. They will just sit in the lowest area of the sidewall and can be brushed into a little container and reused. They shouldn't fall out all over the place. I think the reccomended amount per tire for one of our bikes would be less than an ounce per tire, although I would have to read thier literature to be sure.

Bottom line, I would have to report that I was pleased with the results and don't have any negatives to pass on.

Just a couple of thoughts based on your thoughts:
I believe the amount of weight added by the beads is only two ounces. I have had to add almost that much weight in lead when balancing a tire.
Two ounces compared to ... what? ... twenty pounds? isn't going to have that much effect on turning forces.

I also tend to agree with the skeptics on this concerning just where the bead go and what makes them balance out the tire. It is my opinion (and guess) that they will move to the point farthest from the axle. There is a chance that this might also be the heaviest spot, and this would aggravate any imbalance, not improve it.

I continue to read the stories with interest and amusement, but will stick to lead weights, for now.

I don't know why, haven't read about the science involved, but the beads go where they are needed. It works.
No worries about losing a weight, or balance changing with tire wear.
It's all good.

This works for me:

i am going with the dyna beads on the tires i just mounted, i will report my results.....

 

[propflux01]

I use them on the 'GK. They work great for me, really seems to smooth it out.

Over on advrider.com, Dynabead Holy Wars erupt regularly. Those who run semi-knobbies (like the Conti TKC) seem to feel Dynabeads keep these tires balanced as they wear and make a noticeable difference. Knobbies tend to wear unevenly, so they're probably the toughest test for Dynabeads.

Don, you ride a lot, you're very familiar with your bikes, and are probably the most qualified observer I can think of. Try 'em out and report back, and I for one won't argue with you.

Seat of the pants experience is one thing.
Show me the science.
Unless it works by "magic"
I read the blurb on the Dynabead site and was unimpressed.

Surely someone has checked a wheel on a balancing machine, put this stuff in it and checked it again.

I don't testing on a balancing machine would be conclusive, since the axle is held rigid, unlike the axle on a bike, truck, etc. I'm not sure, but I think the beads need at least a little movement of the axle to get them distributed. I could be wrong about that, but I wouldn't think that the balancing machine would be accepted by many as a real-world test. Only by those who agree with the results, naturally.

I'll be installing them on my bike, if I can ever get that rear tire to seat...

 

[marz]

wearing out from the inside?

lower over all speed?(its a rotating mass.at the very edge of the tire.)although not a lot it doesnt take a lot..

what happens when you come to a complete stop. do they fly around in there and cause bounce.in stopping..

all these questions and more will be answered in the next eppisode of soap

or " the g.s. resources"

All true, it won't work when held rigidly, they even say not to use it on something like a trailer with no suspension, the beads don't go to the right place without some movement....

This technique is not new, it has been in use for decades.
