IMPORTANT NOTICE

•Contact the place of purchase or a bicycle dealer for information on
installation and adjustment of the products which are not found in the
user's manual. A dealer's manual for professional and experienced bicycle
mechanics is available on our website (http://si.shimano.com).

•Do not disassemble or alter this product.

For safety, be sure to read this user's manual thoroughly
before use, and follow them for correct use.

Important Safety Information

•If the clamping strength is adjusted too strong and the quick release lever
cannot be pushed to the CLOSE position, turn the adjusting nut in a
counter-clockwise direction to reduce the clamping strength. When doing
this, do not fully release the adjuster nut. Turn it 1/8 of a revolution, and
then try to push the lever to CLOSE, to set the maximum clamping

strength with which you can push the quick release lever to the
CLOSE position.

Turn 1/8 revolution
at a time

•Use a neutral detergent when cleaning hubs. Other cleaners may damage
the hubs. Do not clean any areas that have been instructed not to be
cleaned.

•Do not clean the hub areas with a high-pressure wash. Water may get
inside the hubs, which can degrade performance.

•Products are not guaranteed against natural wear and deterioration from
normal use and aging.

•For maximum performance we highly recommend SHIMANO lubricants
and maintenance products.

What is a Quick Release?

It is a mechanism that uses a single quick release lever operation on the hub
to enable the wheel to be easily installed and removed.

Quick Release function

When the quick release lever is brought to the closed position, the lever nut
moves inward. The force of this clamps the wheel to the frame and holds the
wheel securely in place.

The clamping strength is adjusted by turning the adjusting nut. When the
nut is turned in a clockwise direction, the clamping strength increases, and
when the nut is turned in a counter-clockwise direction, the clamping
strength decreases.

Open position

2. Open and close the quick release lever with your right hand while

gradually tightening the adjusting nut with your left hand in the clockwise
direction. Continue tightening the nut until you feel resistance with your
hand at the point when the lever is parallel to the hub (as indicated by the
dotted position in the diagram on the right).

3. Grip the rear end with your fingers and use the palm of your hand to close
the quick release lever with as much strength as possible. When closed, the
quick release lever must be in the "CLOSE" position shown below in the
diagram on the right. The side of the lever with the inscription "CLOSE"
must be facing away from the bicycle, and the lever should be parallel to
the rear end as shown below in the diagram on the left.

Guidelines that require replacement, contact the place of purchase or a
bicycle dealer.

WARNING

•Check that the wheels are fastened securely before riding the bicycle.

Using the quick release lever incorrectly may cause the wheel to fall off,
etc. and lead to serious injury due to a fall.

•After reading the user's manual carefully, keep it in a safe place for later
reference.

CAUTION

•Never fasten a wheel to a frame by
rotating the quick release lever as shown
in the diagram on the right.
Simply rotating the lever in a circular
motion will not fasten the wheel to the
frame.
Detachment of the wheel as a result of
improper hub installation can result in
serious bodily injury.

Note

•Do not apply any oil to the inside of the hub. Otherwise, the grease will
flow out.

•If the quick release lever can be easily pushed to the CLOSE position, this
means the clamping strength is insufficient. Return the quick release lever
to the position perpendicular to the bicycle frame and again turn the
adjusting nut clockwise to increase the clamping strength. Push the quick
release lever back to the CLOSE position.

Regular inspections before riding the bicycle

Before riding the bicycle, check the following items. If any problems are
found with the following items, contact the place of purchase or a bicycle
dealer.

•Are the wheels fixed?

•Do the wheels rotate smoothly?

•Are there any abnormal noises?
