The GRX FC-RX610-2 2-piece 2x12-speed crankset combines lightweight construction with exceptional efficiency for mixed terrain riding.
Purpose-built for gravel, its dual chainring setup delivers smooth, responsive power transfer with closely-spaced gear ratios that keep you in the optimal cadence across varied surfaces. The 46/30T configuration provides the versatility you need—enough top-end speed on firm ground, with low gearing for technical climbs and loose terrain. Engineered for riders who demand reliability and performance beyond the road.
