The RideAir Compressed Air Capsule is designed to be a transportable fast inflation device; suitable for seating tubeless tyres, replacing CO2 cartridges, and facilitating fast inflation in pit-stop race scenarios.
It is an interesting KickStarter concept, and one that I was keen to test out.
The functionality of the capsule is simple: you flip open the rubber lid, and using a floor pump or compressor, pressurise the canister to around 200 PSI (13.5 Bar). You can then safely store the canister until you need it. To inflate a tyre, you screw the hose onto the valve (Presta or Schrader), and press the silver button on the canister to release all or part of the charge.
It is effectively like a rechargeable CO2 canister, except that it uses normal air rather than carbon dioxide.
The capsule is easy to use, and robustly made. Releasing the pressure charge is surprisingly easy to regulate too; although there is an element of guessing your tyre pressure, as the gauge on the canister reflects the remaining canister pressure, not that of the tyre.
