Shimano GRX RX820 Crankset 12V 165mm 48/31T Hollowtech

This Shimano GRX RX820 crankset is expertly crafted for compatible 2x12-speed gravel drivetrains, perfect for tackling mixed terrain, fast gravel rides, and competitive racing. The 165 mm crank arms feature Shimano's innovative Hollowtech II construction, while the 48/31T double chainring combination offers a generous 17T range, ensuring you maintain a controlled cadence during climbs, on rough surfaces, and on quicker road sections. This configuration is ideal for riders seeking smaller gear steps than a 1x drivetrain while still having ample range for diverse gravel routes. Be sure to check your frame's bottom bracket shell, front derailleur setup, chainline, rear drivetrain, and required bottom bracket before placing your order, as the bottom bracket is not included.
