Gravel for Everyone.The two-piece Shimano GRX FC-RX610 crank combines low weight with improved efficiency to always cut a fine figure in mixed terrain. The gear ratio of the crankset for 2x12-speed drivetrains is adapted to the different requirements of Gravel use and is ideal for dynamic group rides and aggressive races. Even on rough surfaces, the close gradation with smaller gear steps ensures a consistent cadence and correspondingly good control, which is necessary to maintain the position in the field.
