Subject: Help with silca 'crack pipe' use I can't seem to figure out how to get air from my Park Tool pump through this thing into my aerojacket-covered wheel. The 'crack pipe' threads into the schrader port of the dbl-headed pump I have, but then regardless of what position the lever in back is, all the air escapes out the Presta hole. The adapter doesn't fit into the presta hole at all. I get the sense that even though the Silca adapter is threaded into the schrader hole, there's no pin inside to depress the center of the schrader valve to let air in. Or am I missing something? |
