• If the wheel becomes stiff and difficult to turn, you should lubricate it with grease.
• Do not apply any oil to the inside of the hub, otherwise the grease will come out.
• Special spoke wrenches are available as optional accessories.
• We recommend that you ask authorized bicycle dealers to adjust the spoke
tensions if there is any initial play in the spokes and after the first 1,000 km of
riding.
• Do not use detergents or chemical cleaners to wipe the wheel, otherwise they
may cause the air sealant that has been applied to the joints in the rim to peel
off.
• Do not use detergent or other chemicals when wiping the wheel, otherwise it may
cause the sticker on the rim to peel off.
• Reflectors are also sold separately. Please ask your bicycle dealer for details.

For each sprocket, the surface

should face outward and be
positioned so that the wide

on each sprocket and the A

are aligned.

CAUTION
• Use genuine Shimano spokes, nuts, plugs and washers, otherwise damage to the
rim and hub unit may result.
• The air pressure should be within the range of 200-400 kPa {29-58 psi}.
• Be careful not to overtighten the plugs when adjusting the spoke tensions. If the
plugs are overtightened, damage to the rim may result.
(We recommended that you ask authorized bicycle dealers to make the
adjustments.)
• Puncture repair agents and puncture prevention agents may corrode the rims, so
only use neutral-type agents.

• Do not use rim tape. Rim tape may make it difficult to remove and install the tire,
and the tire or tube may become damaged or the tires may suddenly puncture and
come off, and severe injury may result.

• Check that the wheels are fastened securely before riding the bicycle. If the
wheels are loose in any way, they may come off the bicycle and serious injury
may result.
• Before use, check the wheels to make sure that there are no bent or loose
spokes, dents, scratches or cracks on the rim surface. Do not use the wheel if
any of these problems are found.
• The wheel is designed for cross-country riding. Do not use it for downhill riding,
otherwise the wheel may become bent or otherwise damaged, and accidents may
occur as a result.
• If the quick release mechanism is not used correctly, the wheel may come off the
bicycle and serious injury could result. Read the Service Instructions for the quick
release mechanism thoroughly before use.
• These wheels are designed exclusively for use with disc brakes. Do not use these
wheels with rim brakes.
• Be sure to carefully read the Service Instructions for the disc brakes also.
• Obtain and read the service instructions carefully prior to installing the parts.
Loose, worn, or damaged parts may cause injury to the rider.
We strongly recommend only using genuine Shimano replacement parts.
• Read these Technical Service Instructions carefully, and keep them in a safe
place for later reference.
