Airshot was born in South Wales where its designer was looking for an easy way to inflate stubborn tubeless tires without the need for a compressor. It's simply a blue metal canister that can be inflated to as high as 130psi via its presta valve using a standard track pump. The hose is then attached to the presta valve of a tubeless tire to dump a large volume of air in an instant to help seat stubborn tires. The canister can be taken onto planes in checked baggage (de-pressurized), and is handy to keep in a vehicle for quick inflation at events. The Airshot weighs 435 grams and costs $100 USD / £59.99.

recommended max. is 160psi), screw in the metal valve/chuck onto your tubeless presta valve and turn the blue valve 90º to release the air; twisting this valve will quickly dump a large volume of air at high speed and should promptly seat even the most tenacious tubeless tires. 130psi in the 1.15L bottle translates to 25-30psi in your tire, depending upon your tire and rim combination. If you have a particularly stubborn tire or a gunked-up valve, you can remove the valve core from your tubeless valve and use the adaptor supplied, which screws into the valve itself. I have inflated a number of tubeless tires with the Airshot and it has yet to fail me. Construction is sturdy, finish is top notch, and the metal hardware and components feel like they should hold up for a number of years.
Why don't I just make one myself out of a coke bottle or fire extinguisher?Well, you can if you want, and nobody is forcing you to drop £60 on a blue can; but this does involve sourcing the parts you need, drilling, sealing and the possibility of blowing your own face off if something goes wrong. Of course, this route could work out a lot cheaper, but many people prefer not to trudge the aisles of the local hardware store when they can put their plastic fantastic into use and have the finished unit turn up in the post. I'm the kind of guy who isn't a great mechanic and I like my face, so making something like this at home doesn't float my boat. Plus the Airshot is pretty, may match your bike or accessories and should last for the remainder of your cycling career.
Pinkbike's Take: | The Airshot does exactly what it says on the tin, delivering a huge boost of pressure to seat your tubeless setup. Yes, you could make a cheaper alternative yourself, but people who want to save themselves time and hassle can go straight to the real mccoy. - Paul Aston |

Please stop trying to appear smart and reasonable because there is nothing smart with going Wallmart on everything.
airshot has more volume too by the looks of it if you need to pump it up to 240psi V a max of 160 on the airshot.
Works flawlessly.
I was going to get a compressor but then I realized I lived in a 1 bedroom apartment
The Topeak gauge is £25, bringing costs up to £90. I'm starting to think a regular high volume track pump is the wise buy here.
I had got ever tubeless combo I have ever tried up with a joe blow mountain but never liked the valve connector which leaked like a sieve no matter what you did.
They're also lifetime warrantied, & are generous with the warranty: I took a cheapy airtool comp from about 2002 in & got full credit. Warranty reason? inaccurate gauge. Now that's what I'm talking about.
As for seating tubless, I bought a brass ball valve, tee, NPT to shrader, a NPT to tubing fitting, and some 1/4" tubing, which I stuck into a end of a 2l cap. One of these days I'll get around to doing a writeup, as it's about 100 times easier to put together than the "glue some old prestas into a bottlecap" method
Whats the head connecter like?

Geish… some people. Good luck mate!^^

...I mainly concerned about the the explosive safety issue at a higher psi
They're that good
The Airshot just works and has yet to fail me on any tire/rim combination I've. I thought I'd never use it other than once or twice a year, but after having 3 punctures (too large to seal with sealant, 2 of them too large for tubeless patches) in 3 weeks back in January, the Airshot was a blessing when swapping out tires. Can't recommend enough.
I thought of the homemade soda bottle alternative, but don't trust my McGyver skills enough for me to feel that it'd be safe long term...
You can get a fricken compressor for a little more than that.
Or you can just do what I do, and use those little Co2 canisters.
Not only would it take more than 100 tire inflation's to pay for this thing,
you can buy a MUCH LARGER portable air tank for LESS THAN HALF of what this dude wants for his tiny tank.
Fill it up at a gas station and you're good to go for multiple bead-seatings.

Maybe it is just the 2.8" Nobby Nics and my rims all joining together to be wankers towards me.
Me - Do we have a Soda bottle, I am going to build a compressor thing to put my tires on...
W - Are you sure you know what you're doing?
Me - Sure, I found instructions on Youtube... I just need some valves, duct tape, tubes and the track pump and I'm good to go... I'll only pump it to about 70psi... I'll set up in the kitchen
W - Do you remember when you cut in to your arm with a chainsaw when the workbench you made collapsed?...
*Airshot ordered.
After that I upped my game with a 3l fire extinguisher and tubeless presta valve with some compression BS fittings..... Fire extinguishers can run near 200 Bar pressure so if your able to bounce your body weight on your track pump to get to that,, you really deserve to be shot into orbit..... The fire extinguisher worked a treat.... can hit up 4 tires on tubeless conversions in no time with 150 psi in the bottle... Fire extinguishers are scrapped after so many year so easy to get them and the correct fittings screw straight in.. possibly cost me £10 to do, and made a few for friends too..
I found an old extinguisher from work, so mine cost me the price of a tubeless valve
Even more so you can get online an air compressor for as low as $70.
I personally have the Bontrager Flash Charger and I do love it. I didn't pay $150 for it as I used my commuter bike checks and had a 5% off coupon
So the point being...I don't understand why anyone would get this Airshot and carry around a floor pump and a canister.
Diy ones are fine but you do feel rather nervous pumping it up !

Anyone which has the greatest air volume?
This seems like something that would make more sense in the $49.99 ball park. Not $100.
