Warning
Tyre width section: min 2” / max 2,5”

Warning before using the bicycle:

• Check for proper operation and state of wear of all the components before starting to ride.

• The rims have been made with great dimensional precision. If fitting a tyre on a rim is too easy, it may be too big and this will have significant implications for safety. We therefore recommend using only high quality tyres that require the use of clincher tyre levers and a reasonable amount of strength to fit them. Using a tyre that is too big for the rim may cause the tyre to rupture unexpectedly and cause accidents, physical injuries or even death.
  WARNING! Incorrect rim / clincher tyre coupling may cause it to deflate, burst or detach suddenly and cause accidents, serious injuries or even death.

• Check the condition and pressure of the tires fitted to your Miche wheels.

• Pressure must not exceed the limit of 3bar and 43psi signed behind valve hole.

• A pressure above the maximum written limit may damage the carbon rim and cause irreparably cracks. The inflating pressure of the tyres must NOT exceed the LOWER pressure level between the maximum pressure stated by the tyre manufacturer. Excessive tire pressure reduces the grip of the tire on the road and increases the risk that the tire will unexpectedly burst.

• Inflation pressure that is too low reduces tire performance and increases the probability of sudden and unexpected loss of tire pressure. In addition, premature damage to the rim may occur. The minimum pressure must be equal to 1.3 bar or 19 psi. The minimum pressure of inflation should NOT ever be below the HIGHER level between the value of the minimum pressure specified by the manufacturer of the tire and the one recommended by the manufacturer of the rim. Incorrect tire pressure could cause tire failure or loss of control of the bicycle, resulting in an accident, personal injury or death.

• Check that the wheels are firmly anchored to the frame with the locking item closed in the correct position (Fig. 9). If there is the passing through pin, consult the installation instructions provided by the manufacturer of the bicycle or fork. Attention, an incorrect locking may cause the detachment of the wheel and derive in accidents and serious or fatal injuries.

• Check the tension of the spokes so as to notice any spokes which got loose. In the case spokes are loose, contact a qualified mechanic or special personnel to perform the tensioning. Attention, the use of wheels not centered properly or with spokes broken and/or loosen or damaged may cause an accident, serious injury or death.

• Check that the braking system and the brake pads in the brake calipers are in good state and that the screws on the disc or the locking ring of the disc, depending on your model, are properly locked.

• To the users of more than 78kg weight, Fac Michelin suggests to check the wheels status to the mechanic every two months or every 500km.

• If the total weight of your bike and various parts installed exceeds 105 kg, not used these wheels

• Never wash the pieces with pressure-fed water because water may get through the seals and cause permanent damage to the internal components. We recommend washing components with a sponge, mild soap, and water.

• Salt water environments (as found on winter roads and neat the seaside) can cause galvanic corrosion on most bike parts. Carefully rinse, clean, dry and re-lubricate all exposed parts to avoid damage, malfunctions and accidents.

• If your component shows signs of rust, this means it has to be changed urgently as it might be a sign of damage.

HUBS

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.

When replacing any broken sealed bearings please ensure sealed bearing correct measure and specification are used.

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 bearings:

• 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

SPOKES

The spokes used for the assembly of the wheels have the following sizes and characteristics.

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 thread locker.

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 parameters.
ATTENTION in correct spoke tension, too high or too low, could lead to wheel failure and resulting serious or fatal accident

FITTING THE TUBELESS TYRE

Warning
If you have any doubts about your ability to perform any of the following procedures, seek advice from qualified personnel.
For your safety, always wear gloves and goggles when performing repair and maintenance on your wheels.

Tubeless ready tire. If the tire mounted too easily, the tire is most likely too large.
Warning: oversized tyres may deflate unexpectedly and cause accidents, as well as serious or fatal injuries.
If necessary, use a lever to help insert the tire beads, use a plastic lever so as to avoid damaging the rim. Warning: avoid using sharp objects so as to prevent damage to the tire.
To install the Tubeless ready tire, please follow these simple steps:

• Moisten the base of the rim with soap and water.
• Starting from the valve, insert the firstof the two tyre beads into place, and continue along the entire circumference of the wheel.
• Fit the other bead of the tire and continue around the whole circumference of the rim: check the correct positioning of the tire on both sides of the valve zone. Ensure the correct positioning of the tire moving slightly back and forth the tire.

INFLATING THE TUBELESS TYRE

Warning
If you have any doubts about your ability to perform any of the following procedures, seek advice from qualified personnel.
For your safety, always wear gloves and goggles when performing repair and maintenance on your wheels.

Before inflating the Tubeless ready tire, we recommend that you use the anti- puncture liquid by following these simple steps (Attention, please do not use any liquid, which might contain ammonia):

• Remove the valve cap.
• Using your index finger, gently press the top of the valve so as to ensure there is no air inside the tire.
• Remove the top part of the valve using the appropriate tools.
• Insert the anti-puncture liquid using the appropriate dispenser. Spin the wheel around several times to distribute the liquid throughout the inside of the tire.
• Put the top part of the valve back into place.
• Inflate until you achieve the desired inflation pressure. Make sure the two tire beads are positioned correctly by verifying that the distance between the tire centering line and the margin of the tire is constant around the entire circumference of the wheel.
• Inflate the tyre. Attention, follow the steps in section 2 of the General Indications.
• Put back the valve cap.
• Ride the bicycle for 3-4 kms so as to ensure the liquid inside the tire is evenly distributed.
  When you puncture the tire, the air leakage is slow and not immediate, and in some cases allows you to keep on pedaling back home. Keep in mind that a Tubeless ready tire can be repaired by applying a puncture repair patch or spray, or by inserting an inner tube

INSERTING AN INNER TUBE IN A TUBELESS TIRE IN THE EVENT OF A PUNCTURE

The inner tube must be fitted with a Presta valve that has a 6 mm diameter.

• Deflate the tie.

• Starting from the opposite side of the valve, uncouple the bead from its seat and continue along the entire circumference of the wheel. If you must use a lever to uncouple the tire beads, use a plastic lever so as to avoid damaging the rim and tire.
  Warning: avoid using sharp objects so as to prevent da-mage to the rim and tire.

• Unscrew the valve ring and remove it.

• Drain the puncture prevention liquid from the tire inside.

• Insert the partially inflated inner tube into the tire.

• Starting from the point opposite the valve hole, insert the se- cond tire bead into place and continue along the entire circum- ference of the wheel, be careful not to pinch the inner tube.

• Inflate the inner tube until both tire beads are fitted properly in the correct position.

• Inflate until you achieve the desired inflation pressure.
