• Take care to position of the pawls positions. Lock with power the
mobile side with a torque of 15 Nm, if necessary adjust the hub by
working on the ring (D):
• Unlock the grub screw (E) with a key (B) (Pic. 2).
• Turn the ring in clock sense to drop the sliding, and in anti-clock
sense to rise the sliding. Lock the grub screw (E).
Check the sliding of the wheel.
Please check that the hub is correctly tightened and closed, failure
to do so could lead to a serious or fatal accident.

CHANGE A SPOKE
Warning
If you have any doubt whatsoever your service-repair abi-
lity, please take your bicycle to a qualified repair shop.
Before any maintenance operations on your wheels, al-
ways wear gloves and protection glasses.
To replace a spoke on the 990CARBON Wheels is extremely easy
in both cases, front as well as rear wheels.
• Unscrew the spoke from the nipples with the corresponding
spanner.
• Once it has been unscrewed, slide off the spoke from its own
seat. Before replacing the spoke, draw the spoke to be used for
the replacement in the thread-locker you chose to improve sea-
ling.
Follow the instructions below to replace nipples:
• Starting from the opposite side of the valve, detach both tyre be-
ads from their seating and proceed with the whole circumference
of the wheel. Should you need a lever to remove the tyre beads,
use a plastic lever to avoid damaging the rim and the rubber flap.
Do not use blunt instruments to avoid damaging the tyre.
• We recommend placing the wheel –during the entire operation–
in such a way as to keep the nipple that you want to replace per-
pendicular to the ground.- Using a plastic lever, remove the rubber
flap near the hole of the nipple that you want to replace. Do not
use blunt instruments to avoid damaging the tyre.Once pulled out,
cut the traces of double-sided tape remaining on the rim hole and
remove the nipple from the rim.
• Once removed, insert the new nipple and plug up the hole with
duct tape to seal the hole. Before replacing the spoke, dip the new
spoke into your favourite thread-locking fluid to improve tightness.To
fit the tubeless tyre, follow the instructions of Section V.
Warning
Use only spokes of the same length and characteristics
of those being replaced. Use original spare parts exclu-
sively provided by Fac Michelin Spa.
To ensure the correct spoke tension please follow the indications
below:
• Correct spoke tension for front wheel 900n
• Correct spoke tension for rear wheel, free wheel side: 1100N
• Correct spoke tension for rear wheel, opposite free wheel side:
700N
To evaluate the correct wheel tension, please use a professional
spoke tension gauge, we do not recommend that spoke tension
is estimated manually; please refer to a professional cycle mecha-
nic if you do not own a professional spoke tension gauge. The
correct spoke tension is essential to ensure a ridged and durable
wheelset.
ATTENTION in correct spoke tension, too high or too low, could
lead to wheel failure and resulting serious or fatal accident.

The 990CARBON Wheels quick release has already attached in
the wheel pack.
The quick release lever has two fixed positions:
• OPEN (the text OPEN is visible)
266,5 mm
• CLOSED (the text CLOSED is visible)
265,5 mm
Every time you will use your bicycle, check carefully that the quick
release levers are on the position CLOSE (with the lever in closed
position, on the front side of the quick release the mark CLOSE
must be present) (Pic. 5).
Attention: Please ensure the quick release lever is closed correctly
and in the correct position. Failure to do so could lead to wheel
failure and resulting serious or fatal accident.
All the positions different from the closed position have to be con-
sidered extremely dangerous.
For the correct closing of the quick release:
• Starting from the opened position of the lever, making the nut
contact with the fork manually
• Bringing the lever from the opened position to the closed only
with the hand power (Pic. 6).
• Turn manually with your fingers the quick release nut until its sits
against the cycle dropout, ensuring the quick release lever is sitting
in the "open position" (Pic. 6).
• Don't use any tools (ex: tubes, extensions, ...); the closing stress
has to be felt in the passage from the opened to the closed po-
sition (Pic.6).
• You never have to use the quick release lever as a nut to close the
quick release, because it will injury the quick release (Pic. 7).
Attention, turning the quick release lever to tighten the quick rele-
ase could result in damage to the quick release and cycle frame
dropout, which could lead to wheel failure and resulting serious or
fatal accident.
• Given that the wheels will be used on irregular surfaces, impacts,
hits or a fall can cause also damage which cannot be visible with
fast locking.
If one of these conditions is detected, please visit a qualified me-
chanic or special personnel for an accurate inspection of the lo-
cking, since its damage may cause accidents, and serious or fatal
injuries.
• After every washing, remove the locking from the hub and grease
the pin completely to prevent oxidation.
