Shimano GRX RX820 Crankset 12V 160mm 42T Hollowtech

This GRX RX820 crankset from Shimano is engineered for compatible 1x12-speed gravel drivetrains, perfect for mixed terrain, fast gravel routes, and adventure riding. The 160 mm crank arms feature Shimano's Hollowtech II construction, while the 46T single chainring provides a higher gear option for riders seeking more speed on flatter gravel sections, road transitions, or racing setups. The shorter 160 mm crank length also aids in pedal clearance and bike fit, especially on smaller frames or technical gravel routes. Be sure to check the frame bottom bracket shell, chainline, rear derailleur, cassette range, and required bottom bracket before ordering, as the bottom bracket is not included.
