wheels. Please consult the manufacture of your tires of choice
when inflating your tyres.
• Check the tension of the spokes so as to notice any spokes
which got loose. In the case spokes are loose, contact a quali-
fied mechanic or special personnel to perform the tensioning.
ATTENTION, the use of wheels not centered properly or with
spokes broken and/or loosen or damaged may cause an ac-
cident, serious injury or death.
• Check that the braking system and the brake pads in the bra-
ke calipers are in good state and that the screws on the disc
or the locking ring of the disc, depending on your model, are
properly locked.
• To the users of more than 85kg weight, Fac Michelin S.r.l. sug-
gests to check the wheels status to the mechanic every two
months or every 500km.
• If the total weight of your bike and various parts installed
exceeds 115 Kg, not used these wheels
• Never wash the pieces with pressure-fed water because water
may get through the seals and cause permanent damage to
the internal components. We recommend washing compo-
nents with a sponge, mild soap, and water.
• Salt water environments (as found on winter roads and neat
the seaside) can cause galvanic corrosion on most bike
parts. Carefully rinse, clean, dry and re-lubricate all expo-
sed parts to avoid damage, malfunctions and accidents.
• If your component shows signs of rust, this means it has to
be changed urgently as it might be a sign of damage.
