Their testimonials online reminded me of Split Fire spark plug ads. "After I changed to Split Fires, my mpg went up!" Um, they installed *new* spark plugs to replace old ones. That will usually result in an increase no matter what plug they installed. Ditto, Dyna Beads. I see way, way too many bikes in the shop- some quite well kept - with low tire pressures. If a person were to install the the Dyna Beads, they'd have to remove the valve core, pour in the product, put the core back in and reinflate the tire. I'm stepping out on a limb here to guess most folks would air up a tire to the correct pressure at that point. If the tire were low before, pumping them up to correct pressure alone is going to make the bike handle better, yes? Maybe they work. Maybe they don't. Me? I don't like the idea of adding several ounces of something inside the tire when I can get it to balance with less weight added to a precise place on the rim. eddie

Had another thought on the subject: Anyone here have access to a high speed, spin balancer? Unlike a static balancer, they can rotate the wheel up to running speed before taking a measurement. I'd be curious to see what a computerized spin balancer had to say about a m/c tire with the beads installed. eddie

I believe Motorcycle Consumer News (Dave Searle?) did that recently on DynaBeads or a similar product. The company responded to MCN's less-than-favorable evaluation. MCN's detailed response noted their spin-balancing and road testing in different 2 and 4-wheel vehicles. MCN also noted that the manufacturer submitted no evidence, just pseudo-scientific talk and user testimonials. Regards, Chris

I never saw any real science at all in the Dynabead thing. If your wheel is heavy on one side and is thus throwing that side out of round ellipticaly then any free object is going to want to be there in the tire, which only makes it worse. Best I can see happening is the beeds just keep freewheeling around dampening some of the vibration. I cant see any way that tey can counter the imbalance, only the vibration it induces. I would also tend to believe an independant company like MCN over the manufacturer. I dont know that I am the one to listen to in this but I have 10 years experience building experimental jet engines. Every single spinning part and assembly was balanced on a vert or Horizontal high speed balancer.

Curiouser and curiouser! Loads of us believe that the science used in describing their effect is, well, non real. At least one respected magazine seems to have had a poor experience as well. That said there are reports from some very respectable riders, on this list and others, saying that they work. If I were still in the Jet engine overhaul bussiness I would surely be working on a balance rig to put a wheel in one of the Hofmann or Schenck machines right now. Unfotunately those days are done. So how do we settle this. Proof that they work makes lots of our lives much easier as this is clearly easier than balancing, especially on road trips. Proving they dont work, or within what limitations they work, gives us better knowledge with which to decide for ourselves. Anybody have access to an adequately sufisticated tire balancer as to allow the accelerometers to read only after the tire is up to speed? Are they all like that already? Anybody work on a Horizontal balance machine? How else could we settle this once and for all?

Fred, UNLESS they are in an inner-tube which I plan to re-use, I NEVER try to save and re-use the DynaBeads. Even if you pay 'full-pop' they're about $10 for both wheels, but here's a link to a cheaper way (I have NOT used it, but plan to). This post is copied from a Versys site: "You can get the beads direct from www.foxindustries.com a lot cheaper for about $7.00 lb. just ask for 1.5 mm Zirconium Silicate Beads . Got the info from another motorcycle site and ordered some." I would suggest that the size here is wrong; maybe .15 mm ??? Cheers, Ed

Attachments : That is an easy answer. New tires require new beads. old beads go in the trash with the old tire.
