Shimano GRX RX820 Crankset 12V 160mm 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 racing. Featuring 160 mm crank arms constructed with Shimano's Hollowtech II technology, the 48/31T double chainring combination provides a generous 17T range, allowing you to maintain a controlled cadence on climbs, rough surfaces, and quicker road sections. This setup is ideal for riders seeking smaller gear steps compared to a 1x drivetrain while still enjoying ample range for diverse gravel routes. The shorter 160 mm crank length also enhances pedal clearance and bike fit. Before placing your order, please verify the frame bottom bracket shell, front derailleur setup, chainline, rear drivetrain, and required bottom bracket, as the bottom bracket is not included.
