Miche CARBO GRAFF Manual De Uso Y Mantenimiento página 7

Spare bearings to be used for maintaining these wheels have the
following sizes:
Rear hub
Right side 26x17x5 (6803)
Left side 26x17x5 (6803)
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 end cap (A) (Fig. 1)
• On the same side from which you removed the end cap, insert
a 12mm allen key (M) on the hub axle and, using a classic 17mm
wrench (N), unscrew the end cap (B) counterclockwise (Fig. 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 (Fig. 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 axle (C) and
close the end cap (B) with the 17 mm allen key (N) to a fixing
torque of 15Nm (Fig. 2)
If necessary adjust the hub by working on the ring (F) (Pic. 2):
• Unlock the grub screw (I) with a allen key 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.

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 spoke from the nipples 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 harden the coupling between the spoke and nipple, use a thre-
adlocker medium.
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 assess the correct wheel tension, use a tensiometer: do not rely
on manually felt tension. The correct wheel tension is the key for a
stiff and durable wheel; if you do not have a tensiometer, have the
wheel checked by a qualified mechanic or specialised technician.
Using a tensiometer will ensure the respect of the established
tension parameters.
Abnormal or excessive tension can lead to rim or spoke failures
and can cause accidents, serious injuries or death.
