Shimano GRX FC-RX820-1 Crankset - 12-Speed 40t 110 BCD Hollowtech II BLK

When you're navigating mixed terrain, you need a drivetrain that stays crisp and reliable without weighing you down. The GRX FC-RX820-1 delivers a clean, 1x setup featuring a 40t chainring on a 110 BCD, simplifying shifting and maintenance so you can focus on the trail ahead. Built on Shimano's Hollowtech II platform, it transfers power efficiently across rugged gravel climbs and fast-paced descents.

Who is this for?

Gravel riders and bikepackers who want a lighter, simpler drivetrain that still delivers confident shifting and power transfer on steep grades, loose surfaces, and long backcountry rides. If you value a tidy cockpit and robust performance in challenging terrain, this crankset fits your goals.
