The SKS Airgun is a pump designed for riders who need to inflate their tyres in a hurry, and is particularly suited to race, time trial and triathlon riders who need to get moving again quickly.
The Airgun comes complete with one cartridge - it takes the 16g threaded type CO2 cartridges – a bottle cage mount for the pump, another that holds a spare cartridge, and an insulating sleeve.
The quoted weight of the pump is 105g including the cartridge, separate 16g cartridges weigh in at around 58g each.
The inflator comprises a cast aluminium head with an interchangeable valve assembly that allows it to be used with both Presta and Shrader valves. It is simply a case of unscrewing the valve nozzle and turning the internal seal to the appropriate direction for the type of valve you intend to attach to and replacing the nozzle.
The Airgun differs from the more basic inflators in that it also has a release valve on the top of the head, allowing precise release of the CO2 flow; this is a useful feature as it allows you to test the valve connection with a little blast of CO2 before committing to releasing the contents of the cartridge into the tyre.
