After each long or difficult ride on unpaved terrain, in case of exposure to water
or sand and in any case every 150 km
• Clean the bicycle.
• Lubricate the chain, the freewheel, the gearbox and then remove the excess oil. You
can ask your trusted technician for advice on the best lubricants on the market and
the frequency of maintenance.
• Apply the front brake and move the bicycle back and forth and make sure everything
is in order. If you hear a dull noise with every movement, there are likely to be problems
with the steering: contact the service center.
• Lift the front wheel off the ground and turn it to the right and left and make sure
that the steering is soft. If the steering turns stiff, there are likely to be problems with
the steering: contact the service center.
• Make sure that nuts, bolts, locks and all mechanical and fixing components are
closed and not worn and / or damaged.
WARNING
The bicycle and its mechanical components are subject to wear. The materials of
which they are composed have different life cycles. IT IS RECOMMENDED TO CHECK
THE BIKE PERIODICALLY OR AT LEAST ONCE A YEAR TO EVALUATE THE CORRECT
FUNCTIONALITY AND THE STATE OF WEAR OF THE COMPONENTS AND REPLACE IT
IF NECESSARY.

Flat tire

Do not use the bicycle in the event of a flat or partially flat tire.
If a tire punctures, release the wheel from the hub to remove it and deflate the tire.
Remove the tire with the aid of a tire lever to remove it from the rim. Remove the
perforated inner tube and replace it. Inflate the new chamber slightly and reposition
the tire on the rim above the chamber. Be careful not to pinch the new inner tube
between the rim and the tire. Turn the wheel to make sure that the whole tire is
correctly positioned on the rim and that the chamber is completely inside it. Inflate
slowly to the recommended pressure, checking the position of the tire on the rim.
Reposition the wheel. In case of difficulty, contact the service center which will
replace them.
CAUTION
We recommend that you use only a tire lever for this operation. Otherwise, using a
screwdriver or any other tool, you risk puncturing the inner tube.
Clean the bicycle
Dust the frame with a soft cloth, remove the dirt with a damp cloth and non-abrasive
detergent. Do not use high pressure cleaners. Dry all parts carefully and periodically
apply car wax.
