Shimano GRX is a very popular groupset with gravel riders thanks to its rugged build, optimal gearing, and reliability. GRX 820 is the higher end version in the GRX family, and this crankset is made for riders who prefer a 2x system. This is great for riders who want to make tighter gear steps on a group ride or race. With three different crank lengths to choose from, the GRX 820 crankset offers ultimate customization. The arms include Hollowtech II Technology, keeping the rigidity you need for power transfer while maintaining a low weight. The Shimano GRX 820 Crankset is perfect for any gravel rider or racer to enhance their speed.
