GRX 820 is Shimano’s latest 1×12 gravel groupset, and when Shimano drops a new gravel groupset, you know it’s been obsessed over and refined to perfection over years of development. Combine that drivetrain with Rodeo 3.0X carbon wheels, Ritchey components, Praxis cranks, and a handmade Selle Repente Quasar saddle, and you have a build that goes the distance for road, gravel, and touring.
