Presta valve |
We say he obviously knows nothing because first, he found it necessary to quote the late Sheldon Brown when describing the difference between Schrader and Presta valves (he had to look it up? you're kidding, right?) and second, because of a rather embarrassing faux pas Rocco (and an incompetent content editor at eHow) left embedded in his (mis)information:
"Flip the switch located near nozzle of your pump to the proper setting, Presta or Schrader, if this feature is available. If not, you might have to unscrew, using a counterclockwise motion, your pump's nozzle. A rubber or plastic fitting might pop out of your pump. The side with the point must face out to fill a Presta tube. The side without the point faces out for a Schrader valve..."The "nozzle"? Really? Too bad you couldn't find a reference that used the correct word: it's "chuck," for future reference. But what makes it clear you know nothing, Rocco, is that you got the "pointy side" bit backwards: a Presta valve must slide into the rubber fitting; but in order to pump air through a Schrader valve, you need the little point facing outward to depress the needle valve. Dumbass. |
- You're trying to use a Presta pump on a Schrader valve or vice versa
- You don't have the pump attached right. Interestingly enough, he never mentions unscrewing the valve tip on a Presta before attaching the pump. Whatsamatter, Rocco: never seen a Presta valve?
- Your pump hose is shot (wonder what he thinks might be wrong with a mini or other pump that has no hose...) or it needs a new gauge (ditto about inline gauges).
