Managed to get a pass for a quick ride. Thought I’d dig the mtb out of its winter hibernation. Find out tyres are flat. Start worrying my ride is actually going to get swallowed up by me faffing around with tubeless…..airshot attached….couple of minutes….done. Big thumbs up from me.

I love my Airshot, i do change my tyres quite regular and it is definitely one of the best mtb products i have bought. A must for tubeless riders without access to a compressor in my opinion.

It does work very well – just seems massively over priced for a bottle.

Yeah even though tyre leaked from valve, getting it sorted much easier with airshot this weekend.

I have one but have failed to air up tyres using with the valve core in, had to remove cores on all set ups. The screw connection is then a pain to remove and keep air in before putting core back in. Maybe a qr style fitting would have been better.

I also remove the cores to inflate but never found it hard to keep enough air in when removing the connector.

Possibly but for 60 quid it fits into the not too much category, having used one it’s a great bit of very well made kit – guessing there is a bit of safety testing done on it over and over the coke bottle method. It’s going to be added to my repertoire shortly.

I also remove the core to inflate it, not a problem once its seated then it goes up straight away

I’m guessing you’re using the special attachment for a core less valve? I’ve never had a problem removing it and I don’t worry about keeping the air in. If it did all release it’ll go back up easily with a track pump even with the core fitted assuming the beads sat correctly with the airshot.

You can DIY, not my idea but here’s mine:

Works well.

I go with taking the valve out – with some types of valve I think the force of the air pushes the rubber washer off.

I got the bike shop to do mine. I gave them 2 wheels, 2 tyres and 20 quid. They gave me a fully taped, gunked and inflated set of wheels.

I don’t swap tyres much so I’m happy for someone else to go through the faff for me.

Maybe true but for £10 more you can buy a cheap compressor from screwfix that does the pumping for you.

That won’t pack in my case for travelling though

Got mine for £35 at LBS 8)

be nice if there was a version that screwed onto the top of a sigg bottle or similar.

My track pump only goes up to about 100psi – is that enough to make this work?

You can DIY

A fire extinguisher is a considerably easier option

Junkyard – lazarus

A 7up bottle is considerably easier still; I’ve been using one for years.

people take airshots on holiday with them ?

not as effective IME but yes its cheaper

I’ve got the luggage allowance and the space. Based in 1 place for a week I would, off racing then certainly. Doesn’t need power and cheaper than CO2 in the long run.

how long does it take to inflate with a mini pump ?

I can only get mine up to 110psi indicated, which was more than enough to inflate and seal a 2.3 650b tyre first go so I’d guess you’ll be OK.

I’d use the track pump or the mountain morph but I’ve stayed in places that are set up for bikes, most have a track pump, If I was driving it would be in there 100% with the track pump. Flying you can split this stuff between the group easily enough.

A useful thing that can be taken whats not to like.

A fattish 29er tyre volume a bit over 5 litres according to my shonky calculations. That Airshot can looks about a litre? So 100 psi, ignoring losses, would leave you with 16 psi in the whole thing, which doesn’t sound a lot.

My DIY job originally had 2x 1.5 litre bottles and I only pump up to 60 psi on account of the bottles allegedly exploding above 100. It was OK for some tyres but not for difficult ones, so I doubled up on the bottleage. Now the tyres pop on the rims just great and end up at 20+ psi.

Seen it seat a 2.4×29″ Maxxis just fine to a sensible pressure

Calcs to 20PSI but you get fast delivery to bead the rim, max pressure is 160 which will deliver you 32psi

If you can get 160 in it, that oought to handle anything. Not sure I could get 160 out of my track pump, not that I have anything I’d feel safe trying it on.
