Shimano GRX RX820 Crankset 12V 165mm 46T Hollowtech

This GRX RX820 crankset from Shimano is expertly crafted for compatible 1x12-speed gravel drivetrains, perfect for tackling mixed terrain, fast gravel routes, and adventure riding. The 165 mm crank arms feature Shimano's innovative Hollowtech II construction, while the 46T single chainring provides an enhanced gear choice for riders seeking greater speed on flatter gravel sections, during road transitions, or in racing scenarios. It is designed to pair seamlessly with a compatible Shimano 12-speed rear drivetrain, offering cassette options like 10-45T or 10-51T to suit your desired range. Be sure to check the frame bottom bracket shell, chainline, rear derailleur, cassette range, and required bottom bracket before placing your order, as the bottom bracket is not included.
