MAINTENANCE

Replacing chainrings

• Gear shifting performance will be reduced if the installation positions of the chainrings are incorrect. Be sure to install the chainrings in the

correct positions.

• Use the correct combination of genuine Shimano bolts, chainrings and crank arm, otherwise the large chainring may become damaged by the

bolts.

Outer side

With the marked side of the largest chainring facing outward, set the largest chainring so

that the chain drop prevention pin is positioned under the crank arm.
