The tire valve allows air to enter the tire’s inner tube under
pressure, but doesn’t let it back out unless you want it to.
There are primarily two kinds of bicycle tube valves
(actually, there are other designs, but they are seldom seen
in the US anymore): The Schraeder Valve and the Presta
Valve. The bicycle pump you use must have the fitting
appropriate to the valve stems on your bicycle.
The Schraeder (Shown) is like the valve on a car tire. To
inflate a Schraeder valve tube, just remove the valve cap
and push the air hose or pump fitting onto the end of the
valve stem. To let air out of a Schraeder valve, depress the
pin in the end of the valve stem with the end of a key or
other appropriate object.
The Presta (Shown) has a narrower diameter and is
only found on bicycle tires. To inflate a Presta valve tube
using a Presta headed bicycle pump, remove the valve cap;
unscrew (counterclockwise) the valve stem lock nut; and
push down on the valve stem to free it up. Then push the
pump head on to the valve head, and inflate. To inflate a
Presta valve with a gas station air hose, you’ll need a Presta
adapter (available at your bike shop) which screws on to the
valve stem once you’ve freed up the valve. The adapter fits
the end of the air hose fitting. To let air out of a Presta
valve, open up the valve stem lock nut and depress the
valve stem. Always close the valve stem lock after
inflation.
