The double chainrings are designed with multiple chain bridges to maximize front derailleur performance, while single chainrings use the exclusive X-ODON technology to prevent chain sucks and increase the stability of the chain.
GR4C chainrings are compatible with all RIDEA GR4C cranksets, and Shimano GRX cranks.
