• Re-fit the axel (C) inside hub body with the spacer (Z) (Pic. 6).
• Take care to position of the pawls. Lock with power the mobile
side with a torque of 15 Nm (Pic. 7), if necessary adjust the hub by
working on the ring (H) (Pic. 7):
• Unlock the grub screw (I) with a allen wrentch 2mm (L) (Pic. 7).
• Turn the ring in clock sense to drop the sliding, and in anti-clock
sense to rise the sliding. Lock the grub screw (I).
Check the sliding of the wheel.
Please check that the hub is correctly tightened and

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.
Use only spokes of the same length and characteristics
of those being replaced.
Use original spare parts exclusively provided by Fac Mi-
chelin Spa.
To replace a spoke on the XM 40 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 sealing.
To ensure the correct spoke tension please follow the indications
below:
• Correct spoke tension for front wheel 1100N
• Correct spoke tension for rear wheel, free wheel side 1300N
• Correct spoke tension for rear wheel, opposite free wheel side
900N
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.
Section IV
: Quick release
XM 40.4
Wheels quick release has already attached in the wheel
pack.
The quick release lever has two fixed positions:
• OPEN (the text OPEN is visible)
• CLOSED (the text CLOSED is visible)
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. 11).
Attention, please ensure the quick release lever is clo-
sed 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. 12).
• 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. 12).
• Don’t use any tools (ex: tubes, extensions, …); the closing stress
has to be felt in the passage from the opened to the closed position
(Pic.12).
• 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. 13).
Attention, turning the quick release lever to tighten the
quick release could result in damage to the quick release
and cycle frame dropout, which could lead to wheel fai-
lure 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.
