TO ENSURE SAFETY
TO ENSURE SAFETY
WARNING
• Be sure to follow the instructions provided in the manuals when installing the product.
It is recommended to use SHIMANO genuine parts only. If parts such as bolts and nuts
become loose or damaged, the bicycle may suddenly fall over, which may cause serious
injury.
In addition, if adjustments are not carried out correctly, problems may occur, and the
bicycle may suddenly fall over, which may cause serious injury.
•
• After reading the dealer's manual thoroughly, keep it in a safe place for later reference.
Be sure to wear safety glasses or goggles to protect your eyes while performing
maintenance tasks such as replacing parts.
Be sure to also inform users of the following:
• Downhill bicycle riding and freeriding are inherently dangerous activities. There is a risk
of being involved in an accident that can result in a serious injury or even death. It is
strongly recommended that riders wear protective head and body gear and perform
thorough safety checks of their bicycles before riding. Please remember that you are
riding at your own risk and that you have to consider your experience and your skills
very carefully.
• Check that there are no cracks in the crank arms before riding the bicycle. If there are
any cracks, the crank arm may break and you may fall off the bicycle.
• Be careful not to let the hemming of your clothes get caught in the chain while riding.
Otherwise you may fall off the bicycle.
CAUTION
For installation to the bicycle, and maintenance:
• There is the danger of injury from the tips of the teeth on the chainrings.
NOTE
For installation to the bicycle, and maintenance:
• Use a neutral detergent to clean the crank arm and the bottom bracket. Using alkaline or
acidic detergents may cause discoloration.

TO ENSURE SAFETY
• If pedaling performance does not feel normal, check the bicycle once more.
• Do not wash the bottom bracket with high-pressure jets of water. Water may enter the
bearing section and cause noise or adhesion.
• The gears should be periodically washed with a neutral detergent. In addition, cleaning
the chain with neutral detergent and lubricating it can be an effective way of extending
the life of the gears and the chain.
• The cuffs of your clothing may get dirty from the chain while riding.
• This product is not warranted against damage resulting from improper use, such as
jumping while riding or if the bicycle falls over, except if such malfunctions are caused by
manufacturing methods.
• 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.
The actual product may differ from the illustration because this manual is
intended mainly to explain the procedures for using the product.

About compatibility
INSTALLATION/REMOVAL
For bicycles with rear suspension, make sure in advance that there is no weight applied to the

material due to overtightening or inadequate securing of the components due to
insufficient tightening torque.
