So what would they do on a flat-spotted tyre?

Either that or they have no effect at all.


I've lost weights of my race bike before and its made no difference on the track.


I'd love them to show it actually working on a mock up or something rather than just some diagram (which is a car tyre which does not tilt into corners) - surely if they worked you would see them in MotoGp or superbikes?

I think it's all smoke and mirrors.

Well... beads and tyres. I'd like to see the inside wall of a tyre that has been ridden 5000 hard miles on and off road, then the same with a bike tyre that has had those balls in it.
No damage to the wall or beading in the tyre? Cant see that somehow. Unless theyre special beads which cause no friction at all when being flung out, then there must be wear inside the tyre wall.

WHEN that tyre then becomes unsafe is unfathomable until your ass is sliding down the road..

All IMHO. I dont think it would matter on a modern bike as tyres wear too quickly, but if these are used on a car, maybe that would be a different kettle of fish... or maybe added to an older bike, or bike that has harder compound tyres.. like a tourer.

Whether or not you agree if it works or not, I think most folks would say the price for Dyna-beads is a bit steep for a few grammes of beads. So in the spirit of scientific enquiry I bring you Easy Balance wheel balancing compound...

http://www.tyre-equipment.co.uk/acatalo ... pound.html

Looks pretty much identical to Dyna beads but about a third of the price. One 100g packet would service a front and rear wheel, according to Dyna-Beads filling chart - 29g for a front, 59g for a rear.

So I think I know where my money's going. This website also has a really neat motorcycle tyre valve that is angled to allow easy use of a garage forecourt tyre inflator, here:

http://www.tyre-equipment.co.uk/acatalo ... alves.html

As I've committed myself to fitting my own tyres from now on, this site looks very handy.

Looks good to me M8, this post has just made me realise they never sent the Dyna Beads I ordered (must check bank statement) So I reckon I'll join you and fit these. No idea why they never sent them, but their loss could be my gain

Just had another look and I reckon this stuff is very different to the Dyna Beads. No recommendations for bike tyres at all and the bag apparently destroys itself as the tyre spins and then distributes the stuff around the tyre so it'll be very difficult to split the bag and get the individual weights. As a retrofit it's a non starter as you need to place the entire bag within the tyre

This also seems to be a type of powder rather than beads so I'm at a loss to figure out how a powder would work (the beads were hard enough to get my head around)

As there are no referrals to any bike tyres at all I think I'll stick with the Dyna Beads. Dearer, but still cheaper than a tank of fuel

The latest...............AVOID Scorpion racing like the plague. After I'd given up on the beads ever arriving, this morning I get a special delivery parcel.

Yup inside are 3oz of dynabeads along with a smal plastic tube and a plastic bottle and an invoice for .............................£23.50!!!!!!!!!!!!!!!!! yes for 3oz of tiny ceramic beads they have charged me £23.50 which includes £7.50 +vat for P&P. This is after we agreed a price of £14.95 (which even then was almost a 50% increase on what they said the total cost would be initially)

And please note despite what they might say on their web site....let me assure you there is NO way you'd ever be able to get all these tiny beads out of your tyre and re-use them at tyre change time, it just wouldn't happen they are tiny

I'm just waiting for 09:00hrs when battle will commence!

Rather coincidental - I decided to be brave and go for the EasyBalance option, especially as I'm replacing tyres myself, and my order for 200grams of EasyBalance, plus 5 aluminium angled motorcycle tyre valves (2 bikes worth, plus a spare) came to £38 including VAT and P&P...

I emailed Mr EasyBalance and he said that his stuff is exactly the same as Dyna-Balls (no sniggering at the back there, please). Their website is here and they have a specific motorcycle recommendation.

I haven't received the stuff yet, mind but www.tyre-equipment.co.uk looks like a proper trade site, with lots of interesting tyre-related stuff.

Anyway - all the best, Rich. I'm sure you'll convince them of the error of their ways...

Put the EasyBalance stuff into a couple of tyres last night and it looks (to my eyes at least) rather like bakers yeast - similar colour and small granules less than a millimetre in diameter (possibly half a mm - didn't measure them).

So will they work? I haven't a clue, matey... But I am well pleased with my new angled aluminium tyre valves. They are going to make pumping the tyres up so much easier.

Have you put extra beads in to counteract their weight :smt002

Well I''ve rung them every day since the 3rd March and as yet I cannot even get them to answer the phone. So I reckon they've closed down. In which case at least I recieved something, I've a new 2CT on the front so I'm going to take the weights off the wheel and put the beads in and see what happens. I'll do the same when I swap the rear. This could be the most expensive experiment I've done!

Robbing sods though!

:smt003 Actually, the ali valve weighed 8.5g, the steel one I took off weighed 13g. So we have a (very) minor weight saving...

Doesn't every biker carry one of those in their pocket?

Wouldn't have thought they were meant to be left in situ though. I only put mine on when I want to add air at a garage. (That way you only need one for however many bikes you have)>

I think you're talking about one of those angled adapters BG - I had one until recently - it broke.

I think Mango is on about the valves that are themselves angled. (I've a couple of them waiting to go on).
