Shimano GRX RX820 Crankset 12V 175mm 46T Hollowtech

This GRX RX820 crankset from Shimano is engineered for compatible 1x12-speed gravel drivetrains, making it perfect for tackling mixed terrain, speedy gravel routes, and adventurous rides. The 175 mm crank arms feature Shimano's Hollowtech II construction, while the 46T single chainring provides a higher gear option for riders aiming to accelerate on flatter gravel sections, road transitions, or racing setups. It is designed to be paired with a compatible Shimano 12-speed rear drivetrain, including cassette options such as 10-45T or 10-51T, depending on your desired range. 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.
