Singletrack Magazine, 2016
Watch it seat a tire
Three steps, no tools, no power
1. Connect
Screw the hose onto your tire's Presta valve. For a stubborn tire, take the valve core out and screw the supplied adapter into the valve stem instead.
2. Pump
Close the tap, put your floor pump on the Airshot's valve and fill it to 120 to 160 psi. Never more than 160 psi (11 bar).
3. Release
Open the tap. The rush of air pops the tire onto the rim. Leave the pump on to top up, then put the valve core back if you took it out.
The story
A rider's fix that riders kept
Airshot started in 2014 in Swansea, South Wales. Its designer, a mountain biker, wanted an easy way to seat stubborn tubeless tires without a compressor or a pile of CO2 cartridges.
The answer was simple: a 1.15-liter bottle you fill with your own floor pump, and a tap that lets all that air out in one shot. No batteries, nothing to throw away.
Magazines in the UK, Germany and North America have tested it since 2016, and it keeps coming out on top. Today bike shops and distributors sell it from Norway to Japan, and CycloSpirit.com is its official US store.

New to tubeless?
Why riders ditch the inner tube
- Fewer flats. No tube to pinch, and the sealant plugs small holes while you ride.
- More grip. Lower pressure lets the tire spread over the ground.
- More comfort. A softer tire soaks up the bumps, so long rides wear you out less.
- Lighter wheels. No tube means less weight to spin up.
- Less waste. No tubes or patches to buy, and with the Airshot no CO2 cartridges either.
The hard part is seating the tire the first time. That is the job the Airshot was made for.
Tips and troubleshooting
The tire will not seat
Clean the rim and the tire bead. Wet the bead with soapy water or sealant: a wet tire pops on more easily. Take the valve core out and use the core adapter, since a dirty or narrow core slows the air down. Then fill the Airshot again and repeat. A damaged rim, valve or tire may not seat at all.
How much air goes into the tire?
One shot puts roughly 25 to 30 psi into a mountain bike tire, enough to seat both beads (Pinkbike measured 25 to 30 psi; ENDURO 27 psi in a 29-inch enduro tire). Keep pumping through the Airshot with the tap open to reach riding pressure.
Which pump can I use?
Any bicycle floor pump rated for 160 psi. Do not fill the Airshot with a compressor, and do not use a pump made for lower pressures: it can fail.
Safety
- Check the bottle before each use. Do not use it if it is damaged.
- Never fill it above 160 psi (11 bar).
- For bicycle tires only, and not on a damaged tire or wheel.
- Screw the hose on firmly before you open the tap.
- Keep it out of direct sun and below 122°F (50°C).
- Never pierce or burn the bottle, even empty. Never take it apart while it holds air.
- Store it with the tap open.
Questions

No. You fill the Airshot with the floor pump you already own.

26", 27.5", 27.5+, 29" and 29+ mountain bike tires, and road, cyclocross and fat bike tires, on Presta valves.

No. The Airshot screws onto Presta valves, or into a Presta valve stem with the core taken out.
How much pressure does it hold?
It is tested up to 160 psi (11 atm).
