Shimano GRX RX820 2x12 – Your universal gravel groupset

The 2x12 version of the Shimano GRX RX820 is your perfect choice if you're looking for maximum flexibility when gravel riding. With the 31/48 crankset, you can combine steep climbs with fast sprints. Mechanical shifting precision meets hydraulic braking power. This groupset is the heart of your adventures on gravel, sand, and asphalt.

The right translation for every surface

Whether it's a bikepacking tour, a gravel race, or a relaxed exploration of the terrain, the 2x12 drivetrain offers you two chainrings for maximum flexibility. With the smaller chainring (31 teeth), you can effortlessly conquer even steep gravel climbs. The larger chainring (48 teeth) lets you really pick up speed on paved surfaces. Thanks to the 12-speed cassette, you'll always find the perfect gear.

Reliability you can count on

The mechanical-hydraulic shifting system impresses with its proven Shimano design. The integrated chain stabilizer ensures your chain stays securely in place, even on rough terrain. Hydraulic flat-mount disc brakes provide reliable stopping power in any situation. The entire system is low-maintenance and durable, allowing you to focus entirely on your adventure.
