This black Shimano GRX FC-RX810-2 chainring is the 48T outer ring for the 2×11-speed gravel crankset. It is intended for the matched 48/31T combination, rather than a single-ring conversion.
Aluminum construction and four-bolt Shimano asymmetric mounting identify the ring. Match the crank model and inner-ring pairing before ordering. The quoted 38g figure for the 31T inner ring is not a weight for this 48T outer ring.
