Valvetypes
Cycles may be equipped with one of the
following valve types
(see “Illustr.: Valve types”):
●
Presta valve (PV): secured with a tappet in the
valve, rim hole 6.5 mm/0.26".
●
Dunlop valve (DV): secured with a union nut,
rim hole 8.5 mm/0.33".
●
Schrader valve (SV): secured with a tap- pet in
the valve, rim hole 8.5 mm/0.33".
All three valve types have a valve cap to pre- vent
the valve getting dirty.
10.4 Tyre pressure
On the tyre flank you will find details concerning the maximum pressure for the
relevant tyre. These details are given in PSI, kPa or bar depending on the
manufacturer If the tyre pressure is too high, the inner tubes may burst during your
ride or the rims may break and at an excessively low tyre pressure, the inner tube may
become damaged. Take note of the details concerning the maximum and minimum
tyre pressures.
A tyre pressure corresponding to the indicated lower threshold is suitable for:
●
Light riders.
●
Riding on uneven surfaces.
●
Riding with high level of suspension comfort at higher rolling resistance.
A tyre pressure which corresponds to the indicated upper limit is suitable for:
●
Heavier riders.
●
Riding on even surfaces.
●
Riding with low rolling resistance with lower suspension comfort.
Check regularly that the tyre pressure falls in the indicated zone and is correctly
adapted to the rider and riding plans.
Note: the indications on the maximum and minimum tyre pressure. Fill the tyres with
air at least corresponding to the indicated lower threshold and at the most
