Using a bomb to pump a tire

[JeffD]

I used a bomb for the first time to pump up a tire and I was disappointed in the outcome. I'd like to know whether I was doing something wrong and what other riders experiences are.

 

The tube was being blown up very slowly when I thought it was supposed to be fast. I also got a massive blister on my finger from the cold gas which "burnt" me or gave me a taste of frost bite.

 

The cycle shop from which I bought the attachment and gas canisters from said it was the make that most mountain bikers use but I don't know anymore.

 

Did I do something wrong?

Dont know what you did wrong but bombs work instantly, maybe you didnt open it enough?

[Tumbleweed]

which inflator did you use?

[1hill@aTime]

sounds like it's a deflator

[markStockton]

I think you either had some sort of technical issue or a dud cannister. I've bombed quite a few road and mtb tyres now and must admit I've thrown all my pumps (except for the track pump) away.

 

Both my adapters have a regulator to control the speed of inflation, and the BBB (I think) one has a funky plastic cover that goes over the bomb to protect from the cold.

Ryder also have a nice one that screws onto the tube valve, you then turn the release valve on the inflator. Works like a bomb.

tip from the latest edition of bicycling: insert bombs into an old road tube, and cut off excess rubber. stops the "sticky-freeze". alternatively look for conti or giant bombs which have a kinda polystyrene outer.

MTB = 16g

RB = 12g

But you use can either on both. You must ALWAYS use a glove or something when using the bomb otherwise you will get frost bite! From what you've said it doesn't sound like there was anything wrong with the bomb.

That's Boyle's law.

(P1V1)/T1 = (P2V2)/T2

 

 

 

The pressure inside the gas bomb is way higher than when the gas comes out.

It's volume increases & pressure decreases' date=' so the temperature must

go down.

It's a similar principle to how fridges and air conditioning works.

 

Also, what attachment are you using? Normally a gas bomb will inflat the tyre very quickly. It's what I use to inflate my tubeless tyres [and they need a huge 'kick' of air to make them snap into place']

ha ha Scotty. Use a piece of road bike tube on the bomb to prevent cold sores (more ha ha). and there is a 'way' of doing it properly, ask the bike shop to show you.

beat you to it!

The bike shop can fix cold sores? is that claimable aganst the medical aid?

Using a BOMB to inflate a tyre?????? ........ use C4 or plastics..... but rather leave that to the Palestinians and "fighters" from Iraq..... in their continious search for virgins.

[AuctionLamb]

Only thing that I use to when I get a puncture on the road!

[Climate]

If the tube was inflating slowly, you'll probably find you'd punctured the bomb ... but only just. Make sure the bomb is screwed into the adaptor completely.

I have stopped using bombs since I have found a few that I cant seem to pierce. Never noted the make because I use them so infrequently that once I got round to using them the stickers had worn off. I can low live with the extra minute or so it takes me to pump with a normal pump.
