General Safety Information
– To avoid serious
WARNING
injuries:
• Obtain and read the service instruc-
tions carefully prior to installing the
parts. Loose, worn, or damaged
parts may cause serious injury to the
rider.
We strongly recommend only using
genuine Shimano replacement parts.
• It is important to completely under-
stand the operation of your bicycle's
brake system. Improper use of your
bicycle's brake system may result in a
loss of control or an accident, which
could lead to severe injury. Because
each bicycle may handle differently,
be sure to learn the proper braking
technique (including brake lever
pressure and bicycle control charac-
teristics) and operation of your bicy-
cle. This can be done by consulting
your professional bicycle dealer and
the bicycle's owners manual, and by
practicing your riding and braking
technique.
• These brake levers are equipped
with a mode switching mechanism
to make them compatible with
cantilever brakes and Roller Brakes
or V-Brakes with power modulator.
If the incorrect mode is selected it
may cause either excessive or insuffi-
cient braking force to occur, which
could result in dangerous accidents.
Be sure to select the mode in accor-
dance with the instructions given in
the table below.

• Read these Technical Service
Instructions carefully, and keep them
in a safe place for later reference.
– To avoid
CAUTION
serious injuries:
Be sure to shift the lever one gear at
a time, and reduce the force being
applied to the pedals during shifting.
If you try to force operation of the
shifting lever while the pedals are
being turned strongly, your feet may
come off the pedals and the bicycle
may topple over, which could result
in serious injury.
NOTE:
• For maximum performance we high-
ly recommend Shimano lubricants
and maintenance products.
• Parts are not guaranteed against
natural wear or deterioration result-
ing from normal use.
