For hidden fifth-arm crank installation, use a hex wrench to exchange the position of the anti-chain-drop pin and the black pin, then install the chainring on the hidden-arm crank.

Front Derailleur Extender Notice

STONE front derailleur extender is designed to help adjust the front derailleur position when using very small or very large chainrings.

It can help when using small chainrings such as 46T or 48T, and also when using large chainrings such as 54T, 55T, or larger sizes.

If your chainring is larger than 54T or smaller than 48T, we recommend using this extender to raise or lower the front derailleur and avoid installation or shifting problems.

Please note: The front derailleur extender is not included with this chainring and must be purchased separately.

Compatibility: 10-speed, 11-speed, and 12-speed front derailleur setups
Material: 304 stainless steel
