The XMR hubs are easy to maintain. To do it, proceed as follows:
FRONT HUB
The front hub does not require any particular maintenance.
For any extraordinary maintenance and replacement of bearings,
follow these simple steps:
• Extract the cage chamber (B) (Fig. 1)
Once the chamber successfully removed proceed replacing the
bearings.
• Apply light pressure to the axel (C) using a plastic-edged tool:
apply pressure until the bearing has been totally removed from
its housing including the axel (Pic. 2)
• Once the first bearing has been removed, using special 17mm
diameter extractor, you can then remove the second bearing
(Pic. 2)
Once these have been replaced, proceed in fitting the new bea-
rings:
• Fit the first bearing using a plastic-edged tool: apply pressure
until the soft pad is perfectly fitted within the housing
• Insert the axel (C)
• Centre the second bearing in line with the axel and fit it using
a push bearing that is big enough to contain the axel itself (B).
• Insert the chamber on the axel (Pic. 3)
• Check that the wheel turns freely

• Using allen wrentch 12mm (M), unscrew left stop (O)
Extract the axel of rear hub with the freehub body (E). if necessary
at this point you can:
• Change the bearings (S).
• Grease the cogs with low density grease (C).
• Extract from the axel the freehub body with the relative spacer
(Z) continue the cleaning process of hub. Warning: the bearings
of the freehub body and no replaceable.
• Re-fit the axel inside hub body with the spacer (Z). Take care to
position of the pawls (Pic. 5)
• Insert allen wrentch 12mm (M) on right side of the hub (Pic. 6).
• Stopping left stop (O) with a allen wrentch 12mm (M) locking at
15 Nm (Pic. 6)
• If necessary adjust the hub by working on the ring (H) (Pic. 6):
• Unlock the grub screw (I) with a allen wrentch (L) (Pic. 6).
• Turn the ring clockwise to drop the sliding, and in counter-
clockwise to rise the sliding.
• Lock the grub screw (I) (Pic. 6).

SPOKES REPLACEMENT
Warning
!
If you have any doubt whatsoever your service-repair ability,
please take your bicycle to a qualified repair shop.
Before any maintenance operations on your wheels, always 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 Michelin S.r.l.
To replace a spoke is extremely easy in both cases, front as well as
rear wheels (Pic. 7 and Pic. 8).
• Unscrew the nipples from the spokes with the corresponding
spanner.
• Once it has been unscrewed, slide off the spoke from its own seat.
• Insert the new spoke
• Screw in the nipple with its washer. To avoid a twisting effect, hold
the spoke in place
To solidify the fit between the spoke and nipple, use a medium th-
readlocker.
To ensure the correct spoke tension please follow the indications
below:
• Correct spoke tension for front wheel (disc side) 1000 N
• Correct spoke tension for rear wheel, free wheel side 1100 N
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 mechanic
if you do not own a professional spoke tension gauge. The correct
spoke tension is essential to ensure a ridged and durable wheelset.
Using a tensiometer will ensure compliance with the set load pa-
rameters.
ATTENTION in correct spoke tension, too high or too low, could
lead to wheel failure and resulting serious or fatal accident.
If you have purchased your wheel set already converted to fit Tu-
beless Ready tyres, please read the instructions in sections I, II,
III and IV carefully.
