SHIMANO GRX front derailleur FD-RX820 | 2x 12-speed
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.
The GRX FD-RX820 front derailleur has been designed to accommodate the wider tires on gravel bikes. Compared to Shimano Road derailleurs, the chain line has been moved outwards by 2.5 mm and is 46 mm. Constructed for Shimano 12-speed chains and with its chainring capacity of 17 teeth, the front derailleur harmonises perfectly with the GRX FC820-2 crank with 48-31 teeth. Its Toggle Link construction allows for even more cable routing options and thus a broader frame compatibility. In order to be able to adjust it optimally, it has its own adjustment screw, on which the tension of the Bowden cable can be adjusted.
