Valves
Your CS has a Sclaverand valve (also referred to as Presta valve) (Fig. 131).
This valve is designed to withstand extremely high pressures.
To inflate the tyres of your CS, you first have to undo the small knurled nut
(Fig. 132) a little and depress it carefully until air starts to escape.
Check the fit of the valve body in the stem. If it is not tight, air can leak
out. Do not forget to tighten by hand the valve nut after inflating.
The Sclaverand valve can be filled with a specific adapter with the com-
pressed air pump at the petrol station. A compressed air pump must be
used very carefully as you may otherwise overinflate your tyre and make it
burst.
To let out air, shortly press the knurled nut (Fig. 132).
