When inflating the tire, the cap is first removed, typically with a coin, and then a "portable" dedicated inflator stem is screwed onto the valve stem. Through the inflator, the tire is inflated as usual.

Inflating at home or on the road requires either 6mm air chuck for Presta and Dunlop valves, or an 8mm chuck for Schrader valves. An important advantage of Schrader valves relative to ...
