store it so that it can be referenced at any time.
The following instructions must be observed at all times in order to
prevent personal injury and physical damage to equipment and
surroundings. The instructions are classified according to the degree of
danger or damage which may occur if the product is used incorrectly.
DANGER
Failure to follow the instructions will result
in death or serious injury.
WARNING
Failure to follow the instructions could
result in death or serious injury.
CAUTION
Failure to follow the instructions could
cause personal injury or physical damage
to equipment and surroundings.
Important Safety Information
WARNING
•
In order to ensure child safety for children using this product, children
should be given instruction on the correct use after both guardians and
children have fully understood the following information. Failure to
follow the provided instructions may lead to serious injury.
•
Do not disassemble or modify the product. This may cause the product
to not operate correctly, and you may suddenly fall and be seriously
injured.
•
Before attempting to ride with these pedals and cleats (shoes), make
sure you understand the operation of the engagement/release
mechanism for the pedals and cleats (shoes). SPD pedals are designed to
be released only when intended. They are not designed to be released
automatically when you have fallen off the bicycle.
•
Use only SPD shoes with this product. Other types of shoes may not
release from the pedals, or may release unexpectedly.
•
Use only SHIMANO cleats (SM-SH51/SM-SH56) and make sure that the
mounting screws are tightened securely to the shoes. Failure to securely
tighten the screws may result in a fall in which the cleats do not release.
•
Before attempting to ride with these pedals and cleats, apply the
brakes, then place one foot on the ground and practice engaging and
releasing each cleat from its pedal until you can do so naturally and
with minimal effort.
•
Ride on level ground first until you become accustomed to engaging
and releasing your cleats from the pedals.
•
Before riding, adjust the cleat holding force of the pedals to your liking.
If the cleat holding force of the pedals is low, the cleats may become
accidentally released and you may lose balance and fall off the bicycle.
If the cleat holding force of the pedals is high, the cleats cannot be
easily released.
•
When riding at low speed or when there is a possibility that you might
need to stop riding, (for example, when doing a U-turn, nearing an
intersection, riding uphill or turning a blind curve), release your cleats
from the pedals beforehand so that you can quickly put your feet onto
the ground at any time.
•
Use a lighter cleat holding force for attaching the pedal cleats when
riding in adverse conditions.
•
Keep cleats and bindings out of dirt and debris to ensure proper
engagement and release.
•
Remember to check the cleats periodically for wear. When the cleats
are worn, replace them, and adjust the cleat holding force before riding
and after replacing the pedal cleats.
If the warnings above are not followed, your shoes may not come out
of the pedals when you intend or they may come out unexpectedly or
accidentally, and severe injury may result.
•
Reflectors have to be mounted to the bike at any time as soon as
traveling on public roads. Reflectors are sold separately for models that
do not come with reflectors equipped as standard. For information on
compatible reflectors, contact the place of purchase or a distributor.
•
Do not continue riding the bicycle if the reflectors are dirty or damaged.
Otherwise, it becomes more difficult for oncoming vehicles to see you.
<Models with pins for adjusting gripping force>
•
If you are not sure about how to adjust the pins on the pedals, consult
your place of purchase or a distributor.
•
Raise your feet from the pedals and then slide them sideways to
disengage your feet from the pedals. With one foot firmly on the
ground, practice engaging and disengaging the other foot from the
pedal repeatedly until you become used to the operation, otherwise,
you may fall and be seriously injured. If you cannot get used to this
operation, use the product with spacers installed or the short pins
replaced.
•
Be sure to wear clothing and protective gear which is suitable for the
way in which the bicycle is to be used. Because the pins are long, they
may cause injury if they come into direct contact with your skin.
Notice
•
If pedaling performance does not feel normal, perform an inspection
again.
•
If you experience any trouble with the rotating parts of the pedal, the
pedal may require adjustment. Consult your place of purchase or a
distributor.
•
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.
Regular Inspections Before Riding the Bicycle
Before riding the bicycle, check the following items. If any problems are
found, consult your place of purchase or a distributor.
•
Are the fastening sections fixed securely?
•
Has excess play increased between the cleat and pedal due to wear?
•
Are there any abnormalities when the cleat engages or releases?
•
Are there any abnormal noises?

Cleat types, and using the cleats
WARNING
•
Do not use the pedals or cleats in any way not described in the user's
manual. When the cleat and pedal are facing forwards, the cleat can be
released and engaged with the pedal.
Read the user's manual carefully for instructions on using the cleats.
Failure to follow the instructions may lead to serious injury.
Front
Single release mode cleats (SM-SH51) and multiple release mode
cleats (SM-SH56) are available for use with these pedals.
Read the manual and chose the correct type for your needs, based on
a consideration of bicycle type, riding terrain, and conditions.
Cleats such as the single release mode cleats (SM-SH52) and multiple
release mode cleats (SM-SH55) cannot be used as they lack certain
features, such as stable step-out performance and sufficient holding
force.
How to engage
Press the cleats into the pedal binding with an angled downward motion.
How to release
The release mode can be selected depending on the type of cleat being
used.
(Check the cleat model number and color for the appropriate release
method.)
Single release mode cleats:
SM-SH51
(Black)
Multiple release mode cleats:
SM-SH56
(Silver, Gold / sold separately)
These cleats only release when the
heel is moved
outward
.
They will not release if the heel is
twisted in any other direction.
The cleats can be released by
twisting in any direction.
Upward force may be applied to
the pedal, since the cleat will not
release unless the foot is twisted.
The cleat may release in an upward
direction. Therefore, pulling up on
the pedal may result in the cleat
unexpectedly disengaging.
Therefore, do not use this cleat if
you pull up on the pedals when
riding, or if you perform jumps or
similar in which forces act on the
foot in the direction of cleat
release.
The cleats will not necessarily
release if you lose your balance.
Accordingly, for places and
conditions where it looks as though
you may lose balance, make sure
that you have sufficient time to
release the cleats beforehand.
Although the cleats do release in
directions other than the
horizontal, they will not necessarily
release if you lose your balance.
Accordingly, for places and
conditions where it looks as though
you may lose balance, make sure
that you have sufficient time to
release the cleats beforehand.
When, for example, you are
pedaling vigorously, your heel may
inadvertently twist sideways and
this may cause the cleat to release
accidentally.
Once you have adjusted the cleats,
practice engaging and releasing
until you are fully familiar with the
amount of force and foot angle
required. An unexpected release
may cause you to fall off the bicycle
and serious injury may result.
If the characteristics of multiple
release mode cleats are not
sufficiently understood or used
correctly, they are more likely than
single release mode cleats to
release unexpectedly.
Once you have adjusted the cleats,
practice engaging and releasing
until you are fully familiar with the
amount of force required in each
direction. An unexpected release
may cause you to fall off the bicycle
and serious injury may result.
Notice:
It is necessary to practice releasing until you become accustomed to the
technique.
* In multiple release mode, releasing by lifting your heel requires
particular practice.
<When installing cleat spacers>
•
The cleat spacer is only compatible with SHIMANO cleats (SM-SH51 /
SM-SH56).
•
Only use cleat spacers in the following cases. When using spacers, use
only one per SPD compatible shoe.
