NOTE
:
The required air pressure can vary by manufacturer and the model of tyre. Follow the manufacturer's instruc-
tions for the correct tyre air pressure on the tyre side wall. If you have any questions, please contact your
specialist bicycle dealer. He or she will be pleased to advise you.
Some tyre pressures are indicated in “psi”. Convert the tyre pressure into bar using the following table.

Check the tyre pressure using a tyre pressure gauge. Suitable devices are available from specialist shops.
For details of their use, please refer either to the user manual supplied with the gauge, or consult your local
dealer.
For tyres with automatic valves you can also check and correct the air pressure at filling stations.
• If the pressure is too low: Increase the inflation pressure using a suitable pump.
• If the pressure is too high: Release the necessary amount of air via the valve, then check the inflation
pressure again.
NOTE
:
A bike pump with pressure gauge allows you to check the inflation pressure while inflating. First allow a little
air to escape from the tyre, then inflate to the required value.
There are various types of valves (see section 4.7, Tyres). All valves can be fitted with a dust cap. In the
case of a Schraeder (Auto) valve or Dunlop valve, the pump head can be connected directly after removing
the cap. In the case of a Sclaverand (French) valve you first have to loosen the small lock nut on the valve
as far as it will go, then tighten it again completely after inflating the tyre. Have the use of the valves ex-
plained to you by your dealer.

Checking other points
1. Check whether there are any other loose items such as twigs, substance residues or similar items in
your wheels.
2. Remove such items carefully.
3. If you have had spoke reflectors fitted, check that these are firmly fitted in place.
4. If they are loose, please remove them completely.
5. Check whether your wheels have been damaged by these loose parts.
7.2
Inspecting the saddle and saddle post
WARNING Danger from serious falls
If the insertion depth of the saddle post is too small, it may be released from the frame while you are
riding and lead to dangerous situations, falls and accidents. Furthermore, if the insertion depth of
the saddle post is too small, this may cause damage to the saddle post and frame.
