How to check for air leaks?
If anomalous pressure losses occur, check:
- the tyre bead surface
- the outer surface of the tyre (tread and sidewalls);
- the surface of the bead housing on the rim.
- Make sure the extension (Fig. 14 - D) is firmly screwed onto the rim by the ring (Fig. 14 - E).
- Make sure the valve (Fig. 14 - C) is firmly screwed onto the extension (Fig. 14 - D).
Remember that you must always check the tyre inflation pressure before you use them every time.

Notes
Check that the tube valve is compatible with the rim. If it is not, contact the nearest dealer
to receive more precise information on compatible tubes.
- THE USE OF RIM TAPE IS NOT REQUIRED.
•
Deflate the tyre.
•
Unscrew the valve ring (A - Fig. 15) by hand and remove the valve.
•
Introduce a partially inflated presta inner tube into the tyre (Fig. 16).
•
Fit the other bead of the tyre into the rim groove (Fig. 17) starting from the point
opposite the valve, and continue around the whole circumference of the rim, taking care
not to pinch the tube.
• Wet the tyre bead and rim profile with soap and water.
