This is Shimano's outer chainring for the GRX FC-RX600-11 gravel crankset. The 46-tooth ring uses a 110mm, asymmetric 4-arm bolt circle and pairs with the crankset's 30-tooth inner ring to form a wide-range 2x11-speed gravel drivetrain. Machined from aluminum, it keeps the round ring shape of the original Shimano design.
As a genuine Shimano replacement or spare part, it drops into an existing FC-RX600-11 crankset to restore worn shifting performance or let a rider keep a spare on hand. Finished in black, it matches the rest of the GRX groupset and suits riders who want a factory-correct chainring for their gravel setup.
