FRONT HUB
The front hub does not require any particular maintenance.
For any extraordinary maintenance and replacement of bearings, fol-
low these simple steps:
• Remove the contact item (A) (Fig. 1)
• On the same side from which you removed the contact item, insert
a 12mm Allen wrench (M) on the hub pin and, using a classic 17mm
wrench (N), unscrew the contact item (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, checking
the correct smoothness.
• Insert the hub axel (C) again and tighten the contact item (B) with the
17mm wrench (N) at the tightening 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 wrentch 2mm (L).
• Turn the ring in clock sense to drop the sliding, and in counter-
clockwise to rise the sliding.
• Lock the screw (I).
• 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.

• Insert allen wrentch 12mm (M) on right side of the hub (Pic. 4).
• Using adjustable wrentch (N), 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.
• 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 (C) inside hub body with the spacer (Z). Take care to
position of the pawls (Pic.4).
• Insert allen wrentch 12mm (M) on right side of the hub (Pic.6).
• Stopping left stop (O) with adjustable wrentch (N) 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 2mm (L) (Pic. 6).
• Turn the ring in clock sense to drop the sliding, and in counter-
clockwise to rise the sliding.
• Lock the screw (I) (Fig. 6
• Check the sliding of the wheel.
Please check that the hub is correctly tightened and closed, failure

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 spoke from the nipples with the corresponding span-
ner.
• Once it has been unscrewed, slide off the spoke from its own seat.
• Insert the new spoke
• Screw nipple with washer
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 (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.
ATTENTION in correct spoke tension, too high or too low, could lead
to wheel failure and resulting serious or fatal accident.
