With the GRX, Shimano brought the first gravel-specific shifting group onto the market. Since then, the range of uses and the range of gravel bikes has expanded significantly. Shimano takes this development into account by also expanding the range of the GRX group. With 12 sprockets on the rear wheel and the option to choose between a 1-speed and 2-speed setup, you can adapt your drive even better to your needs.
