With the GRX, Shimano launched the first gravel-specific groupset on the market. Since then, the range of applications and the range of gravel bikes has expanded significantly. Shimano has responded to this development by expanding the range of the GRX groupset. With now 12 sprockets on the rear wheel and the option to choose between a 1x and 2x setup, you can adapt your drivetrain even better to your needs.
