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 shifter operation.
If gear shifting operation does not feel smooth, consult the place of purchase for assistance.
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.
Grease with SIS SP41 Grease (Y04180000) the inner cable and the sliding portions of the outer casing before
use to ensure that they slide properly.
Use an OT-SP41 cable and a cable guide (SM-SP17 / SP18) for smooth operation.
A special grease is used for the gear shifting cable. Do not use Premium Grease or other types of grease,
otherwise, they may cause deterioration in gear shifting performance.
Use an outer casing which still has some length to spare even when the handlebars are turned all the way to
either side. Furthermore, check that the shifter does not touch the bicycle frame when the handles are turned
all the way.
If gear shifting adjustments cannot be carried out, check the alignment of the derailleur hanger and check if
the cable is lubricated or if the outer casing is too long or too short.
