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.

Instructions carefully, and keep them

– 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.
