SHIMANO GRX FC-RX610-2 Hollowtech II Black Crankset 2x12-Speed 46/30T 

The Shimano GRX FC-RX610-2 Crankset is designed to provide performance and value over mixed-terrain gravel riding in a 2x12-Speed platform. Pair it with a wide-range cassette for big adventures or closer gear steps for near-perfect cadence. Slightly narrowing the chainring allows for a narrower 12-speed chain to ensure smooth and precise shifting. The adventure awaits, grab a gear and start pedaling.
