At what price peace of mind?

Lying somewhere between DIY kits and tubeless seating pumps from Bontrager and Topeak on the I might just be maimed spectrum, Britain’s own Airshot system consists of a pump-pressurised vessel with a high-pressure hose and valve intended to quickly, easily, and safely seat tubeless tyres.

While tyres and rims have improved considerably over the past several years, there are always combinations (usually involving used tyres covered in dried sealant) that give us fits.  Rather than resorting to frantic curse-interspersed pumping, Airshot would have you pressurise their portable alloy bottle to ~150psi, and then unleash the furies in a single blast.  It’s essentially a refined version the forum-favourite DIY methods involving soda bottles – or a BYOP[ump] version of the Singletrack-Recommended Bontrager Flash Charger or Topeak’s new Booster. Unlike CO2 cartridges, if the Airshot fails to seat on the first go, there’s plenty of opportunity for a do-over.

As many mechanics know, one of the easiest ways to allow more air through the valve more quickly is to remove the Presta core. Airshot has this approach covered – the kit comes with an adapter that screws directly into the valve stem (core removed) for more free air flow. That’s a little piece that might sell well if offered separately.

So how much is peace of mind and the absence of faff worth? Airshot reckon £60 – 40% less than the Bonti Flash Charger. What say you all?
