Anyone for R100 "bombs" ea?

[AndreZA]

This is nuts $99 for 10 air bombs just because they stay in your tubes/tyres longer.

 

 

 

Stayfill Air canisters

[DaLoCo]

Well, if it stays for four years as they claim, and I do not have to wheeze around with my handpump.....bargain. It does add about 48 grams in weight....so not sure the weight weenies will approve

[bduplessis]

Een doring en dis in elk geval in sy m@$r.

[porky]

Sounds to me, like a "solution" to a "non existant" problem.

 

.............but dont worry, the yanks will be queing up to buy it.

[Schwynn]

I get 2 to 4 punctures on one ride, so it's of no use to me. I don't even buy bombs any more. It got to expensive.

[The Worm]

I'd rather just pump my tire before each ride. although I generally don't need to. UST rims with UST tires rock.

[Red Zone]

Probably just nitrogen in the bomb, Nitrogen has a larger molocule, so it doesnt leak through the tyre or tube as easily. I think aircraft tyres and possibly Gp / Moto Gp tyres use Nitrogen.

[Azonic]

Useless idea. Which cyclist rides a year without checking tyre pressure? Just check your wheels before each ride, and if need be, give it a 10 second pump-up. Free, mahala. Money making scheme, and I am sure some suckers would still buy it.

Larger molecules? What kind of gas it it?

I wonder if/how it reacts with Stan's?

 

The rest of that webpage has quite a high bullsh!t factor, I think.

If it is nitrogen, which I am inclined to agree with you on, it should play havoc with slime

But Nitrogen makes up 78% of our air anyway:

Permeability of most rubbers to gases vary from gas to gas; differences between air and pure nitrogen is negligible; there could be a significant difference between CO2 and nitrogen.  CO2 is much cheaper than nitrogen, but diffuses though rubber more easily as I recall.  Oh, and CO2 does f*%k up Stans quite quickly, so after a few "bombs" into your tubeless tyres it might be a good idea to refill the Stans..

i agree, a few pumps now and again from a normal pump is FREE!

dont know anybody who rides without pumping tyres for a year!

and anyway IM changing tyres constantly or flying for races so I need to deflate the tyre anyway.

I guess somebody just thought they had found a nice gap in the market. But a good product is one that SELLS...good luck to them

 

[Woofie]

yep. I agree with you guys. It must be nitrogen in there for them to work like that.

 

I could imagine it working ok for a mtb with low pressure, but on my road bike I need to always add a bar or 2 each time I go riding. There is no way that nitrogen is not going to escape under that pressure.

 

 

 

The one thing I like about those stayfill bombs is the last one liner on their website.

 

Go and read it

I bet my Fart gass Still have the biggest Molecules and If I could somehow compress it into my tyres no thorn would want to puncture my tires at least not twice..
