With the Tacx CO2 Inflator you can restore the tyre pressure with little energy, compared to the use of a hand pump. The black dose-measuring button guarantees the right pressure at all times and the cap protects the valve adapter from dirt. The plastic insulation sleeve protects your hands from extreme cold during use. The CO2 Inflator is suited for Presta and Schrader valves and 16 grams CO2 cartridges (threaded). The cartridges are also available separately.
