Regarding Compatibility of CY4-SHC

Dear customer

CY4-SHC series inner chainrings are designed for Shimano cranks.
Each chainring is designed to function only when the specified crank and outer chainring are used.
CY4-SHC may require the use of CAPACITY BOOSTER. Please refer to the compatibility table below. (*CAPACITY BOOSTER works with Shimano original inner rings as well.)
