Warning before using the bicycle it is necessary to:
• Check for proper operation and state of wear of all the compo-
nents before starting to ride.
• The rims have been made with great dimensional precision. If
fitting a tyre on a rim is too easy, it may be too big and this
will have significant implications for safety. We therefore re-
commend using only high quality tyres that require the use of
clincher tyre levers and a reasonable amount of strength to fit
them. Using a tyre that is too big for the rim may cause the tyre
to rupture unexpectedly and cause accidents, physical injuries
or even death.
WARNING! Incorrect rim / clincher tyre coupling may cause
it to deflate, burst or detach suddenly and cause accidents,
serious injuries or even death.
• Check the condition and pressure of the tires fitted to your whe-
els. 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 qua-
6 CONTACT GR / MICHE.IT
lified 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 brake
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 120 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 components 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 exposed 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.
