TO ENSURE SAFETY
Be sure to also inform users of the following:
For installation to the bicycle and maintenance
Be sure to follow the instructions provided in the manuals when installing the product.
Only use SHIMANO genuine parts. If a component or replacement part is incorrectly assembled or adjusted, it
can lead to component failure and cause the rider to lose control and crash.
Wear approved eye protection while performing maintenance tasks such as replacing components.
Never use alkali- or acid-based solvents such as rust cleaners. If those solvents are used the chain might break
and cause serious injury.
Clean the chain with an appropriate chain cleaner regularly. Intervals between maintenance depend on the
use and riding circumstances.
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.
Check the chain for any damage (deformation or cracking), skipping, or other abnormalities such as
unintended gear shifting. If any problems are found, consult your place of purchase or a distributor. The chain
may break, and you may fall.
Install the inner cover correctly. If it is not installed correctly, the axle may rust and become damaged, and the
bicycle may fall over and serious injury may occur as a result.
The two left crank arm screws should be tightened alternately in stages rather than each fully tightened at
once. Use a torque wrench to check that the tightening torques are within the range of 12 - 14 Nm. Also,
after riding approximately 100 km (60 miles), use a torque wrench to re-check the tightening torques.
Thereafter, continue to check the tightening torques periodically. If the tightening torques are too weak or if
the mounting screws are not tightened alternately in stages, the left crank arm may come off and the bicycle
may fall over, and serious injury may occur as a result.
Re-checking the tightening torque of the crank arm is necessary when the crank arm is subjected to strong
blows from a fall. If riding when the tightening torque is weak due to a strong blow, the crank arm could
detach and you may fall off the bicycle.

Be sure to also inform users of the following:
Be careful not to touch the teeth of chainrings. There is a danger of injury.
TO ENSURE SAFETY
5
Be sure to also inform users of the following:
For installation to the bicycle and maintenance
Be sure to keep turning the crank arm during the shift lever operation.
When the chain is in any of the positions shown in the figures, the chain may come into contact with the
chainring or front derailleur and generate noise. If noise is a problem, shift the chain onto the next largest
sprocket or the one after it.
Double
Chainring
Sprocket
Check that there is no excess play or looseness in any fastening sections before riding the bicycle. Also, be sure
to retighten the crank arm and pedals at periodic intervals.
Use a neutral detergent to clean the crank arms and the bottom bracket. Using alkaline or acidic detergents
may cause discoloration.
If pedaling performance does not feel normal due to an abnormal noise, etc., contact your place of purchase.
Do not wash the surrounding area of the bottom bracket with a high-pressure wash. Water may enter the
bearing section and cause noise or adhesion.
If you feel any excess play in the bearing section, the bottom bracket should be replaced.
The chainrings 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 chainrings and the
chain.
The cuffs of your clothing may get dirty from the chain while riding.
This product is not warrantied against damage caused by improper use, abuse, or issues resulting from a crash,
unless the circumstance was caused by a manufacturing problem.
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.
When installing the pedals, apply a small amount of grease to the threads to prevent the pedals from seizing.
Use a torque wrench to securely tighten the pedals. Tightening torque is 35 - 55 Nm. The right crank arm has
a right-hand thread, and the left crank arm has a left-hand thread.
If the bottom bracket shell is not parallel, gear shifting performance will drop.
If the chain keeps coming off the gears during use, replace the chainrings and the chain.
When installing the left- and right-hand cups, apply grease and be sure to install the inner cover. Otherwise,

If a squeaking noise is heard coming from the bottom bracket axle and the left crank arm connector, apply
grease to the fastening section, then tighten it to the specified torque.
Only use chainring combinations listed below. If other chainring combinations are used, it can create poor
shifting and cause the chain to jam, resulting in damage to the bicycle.
