General Safety Information
WARNING
– To avoid serious injuries:
• Obtain and read the service instructions carefully
prior to installing the parts. Loose, worn or damaged
parts may cause the bicycle to fall over and serious
injury may occur as a result. We strongly recommend
only using genuine Shimano replacement parts.
• Read these Technical Service Instructions carefully,
and keep them in a safe place for later reference.
Note
• For smooth operation, use the specified outer casing
and bottom bracket cable guide.
• Because the high cable resistance of a frame with
internal cable routing would impair the SIS function,
this type of frame should not be used.
• The sliding surfaces of the inner cable and outer
casing should be greased before use.
• The shifting lever can be installed to handlebars with
diameters of 19.0 – 22.0 mm.
• Operation of the levers related to gear shifting should
be made only when the front chainwheel is turning.
• Parts are not guaranteed against natural wear or
deterioration resulting from normal use.
• For any questions regarding methods of handling or
maintenance, please contact the place of purchase.

Installation of the lever
When installing the components to carbon frame/handle
bar surfaces, verify with the manufacturer of the carbon
frame/parts for their recommendation on tightening torque
in order to prevent over tightening that can cause damage
to the carbon material and/or under tightening that can
cause lack of fixing strength for the components.
The illustration shows an explanation of the case where
the shifting lever is installed to drop handlebars.
Install the front lever in the same way.
