I’ve been going thru my under seat bags in preparation for the upcoming season. In one I found a Planet Bike Red Zeppelin CO2 inflator. Fortunately, I’ve never had the occasion to use it while out on a ride
. I was checking it out an saw that it’s threaded for both Schrader and Presta valves. What I don’t see is anything that would depress the “pin” of the Schrader valve to allow the CO2 to inflate the tube. Am I missing a part or am I wrong to believe that the pin needs to be depressed to allow the tube to fill?
