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. www.airshotltd.comPerformance
You can inflate the Airshot using any normal track pump, or even a mini-pump if necessary, but for safety reasons, a compressor is not recommended. Once pressurized to 130psi (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|
