There are various types of valve. All
valves can be fitted with a dust cap.
After removing the cap you can place
the pump head directly on the valve in
the case of either a Schrader valve or
the so-called Presta valve. On a racing
bike valve you must first screw the little
locking screw out of the valve until the
stop and tighten it again after inflat-
ing the tyre. Get your dealer to demon-
strate operation of the valves to you.
