TYRE VALVES
There are two kinds of bicycle tube valves in common
use - 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
is like the valve on a car tyre. To inflate a
Schraeder valve tube with compressed air or with a
bicycle pump, remove the valve cap and push the air
hose or pump fitting on to 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
valve has a narrower diameter and is only
found on bicycle tyres. To inflate a Presta valve tube
using a Presta headed bicycle pump:
●
remove the valve cap
●
unscrew (anti-clockwise) the valve stem lock nut
●
push down on the valve stem to free it up
●
push the pump head on to the valve head,
and inflate.
BICYCLE SUSPENSIONS
Some bicycles come equipped with suspension systems.
There are many different types of suspension systems.
If your bicycle has a suspension system ask your bicycle
retailer to explain care and use. Return your bicycle for
regular maintenance and adjustment of the suspension
system.
