The Shimano GRX FC-RX820-1x12 crankset strikes a harmonious balance between shedding weight, enhancing efficiency, and accommodating the diverse gear requirements of mixed-terrain cycling. When combined with either a 10-45T or 10-51T cassette and complemented by 40T and 42T chainrings, cyclists have the flexibility to select between tighter gear ratios for precision or extended range for versatility. With crank arm lengths available in 170mm, 172.5mm, and 175mm, the FC-RX820-1 allows riders to fine-tune their setup to match their specific preferences.
