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.
The FC-RX610 crankset offers all the features of its big sister RX820 and also impresses with an excellent price-performance ratio. Although it weighs a few grams more due to the slightly simpler choice of materials, its stiffness and functionality are at the same high level. The workmanship is also very high quality and adapted to the intended use, so that the crank will be your faithful companion for many kilometers. With the large 46-tooth ring, you can make good speed on the flat, but also climb longer ascents with ease with the small 30-tooth ring. The chainline has been shifted outwards to make room in the frame for wider tires. Nevertheless, the Q-factor has remained pleasantly narrow at 151 mm. The typically excellent Shimano workmanship and aerodynamically shaped elements on the outer chainring make the crankset a long-lasting and reliable companion on your tours.
