TO ENSURE SAFETY

TO ENSURE SAFETY
WARNING

••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.

Be sure to also inform users of the following:

••Be careful not to let the hemming of your clothes get caught in the chain while riding.
Otherwise, you may fall off the bicycle.

NOTICE
Be sure to also inform users of the following:
••If gear shifting operations do not feel smooth, wash the shifting unit and lubricate all
moving parts.

••When the chain is in any of the positions shown in the figures, the chain may come into
contact with the front chainring or front derailleur and generate noise. If noise is a
problem, shift the rear sprocket to the next largest gear or the one after it.

Double (12-speed)

Front chainring

Rear sprocket

For installation to the bicycle, and maintenance:

••For frames with suspension, the chainstay angle will vary depending on whether the
bicycle is being ridden or not being ridden.

4
TO ENSURE SAFETY

••When the bicycle is not being ridden and the chain is positioned on the front largest
chainring and the rear smallest sprocket, the outer plate of the front derailleur may
touch the chain.

••Use an OT-SP41 outer casing and a cable guide for smooth operation.

••If excess play in the links is so great that gear shifting adjustments cannot be made,
replace the shifting unit.

••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.

NOTICE
••When installing parts onto a carbon frame/handlebar, confirm the recommended
tightening torque with the carbon frame or handlebar manufacturer. This will prevent
damage to the frame/handlebar due to over-torquing or inadequate securing of the
components.

Installing on bicycles with rear suspension

For installation and SIS adjustment procedure, make sure to test the shifting operation while
the suspension is in the approximate geometry it will be ridden in.

Checking gear shifting and fine tuning

After the cable is installed and adjusted, operate the shifting lever to check the gear shifting
performance. (This also applies if gear shifting becomes difficult during use.)
Refer to the table when fine tuning. Turn 1/8 of a turn for each adjustment.

If the chain falls to the crank side Turn the high limit screw clockwise.

Tighten the cable. If this does not improve the

If gear shifting is difficult from the smallest
situation, turn the high limit screw

counterclockwise.

If gear shifting is difficult from the largest Turn the low limit screw counterclockwise. If this
