The XGRAFF 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:
• Remove the contact item (A) (Pic. 1)
• On the same side from which you removed the contact item, in-
sert a 12mm Allen wrench (M) on the hub pin and, using a 17mm
wrench (N), unscrew the contact item (B) counterclockwise (Pic.
2)
• Remove the axle from the side of the disc brake.
Once the axle has been removed, you can replace the bearings:
• Use a special puller for 17mm holes and remove both bearings (S)
from their seat (Pic. 3)
Once these have been replaced, proceed fitting the new bearings:
• Using a special tool, insert both new bearings in their seat, che-
cking the correct smoothness.
• Insert a 12 mm Allen key (M) and reinsert the hub pin (C) and close
the clash (B) with the 17 mm spanner (N) to a closing torque of
15Nm (Pic. 2).
If necessary adjust the hub by working on the ring (F) (Pic. 2):
• Unlock the grub screw (I) with a allen wrentch 2mm (L).
• Turn the ring clockwise to decrease the smoothness of the mo-
vement, and counterclockwise to increase the smoothness of
the movement.
• Lock the screw (I).
• Check the sliding of the wheel.
Please check that the hub is correctly tightened and closed, fai-
lure to do so could lead to a serious or fatal accident.

by Fac Michelin S.r.l., involves the expiration of the guarantee.
REAR HUB
The rear hub requires cleaning and lubrication of the ratchets in
the freewheel body.
For any maintenance:
• Insert allen wrentch 12mm (M) on right side of the hub (Pic. 4).
• 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).
• Check the sliding of the wheel.
Please check that the hub is correctly tightened and closed, fai-
lure to do so could lead to a serious or fatal accident.

� 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 tho-
se 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
threadlocker.
To ensure the correct spoke tension please follow the indica-
tions 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 me-
chanic 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.
