Notice
Notice
Be careful not to get water into the E-TUBE ports.
The components are designed to be fully waterproofed to withstand wet weather riding conditions; however,
do not deliberately place them into water.
Do not clean the bicycle in a high-pressure wash. If water gets into any of the components, operating
problems or rusting may result.
Handle the components carefully, and avoid subjecting them to strong shock.
Do not use the thinners or harsh solvents to clean the products. Such solvents may damage the surface. When
cleaning the products, use a cloth moistened with a neutral detergent diluted with water.
If gear shifting operations do not feel smooth, wash the shifting unit and lubricate all moving parts.
If the chain keeps skipping during use, replace the gears and chain at the place of purchase.
If you hear abnormal noise as a result of excess play in a pulley while riding, you should replace the pulley at
the place of purchase.
The gears should be periodically washed with a neutral detergent. In addition, cleaning the chain with neutral
detergent and lubricating it can be an effective way of extending the life of the gears and the chain.
Contact the place of purchase for updates of the component software. The most up-to-date information is
available on the SHIMANO website.
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.

About the RD protection function
About the RD protection function
The RD protection function will activate to protect the system when it is subjected to a strong impact such as a
fall.
When the RD protection function is activated, the links move left and right and the rear derailleur automatically
recovers, so no operations are required.
