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. To meet the different requirements of Gravel riding, the crankset for 1x12-speed drivetrain systems offers a range of gear ratio options. Be it a tighter gear gradation or maximum bandwidth, two different chainring sizes (38 or 40 teeth) and the choice between a cassette with 10-45 or 10-51 teeth (CS-M7100-12, sold separately) makes it possible to serve the individual needs of the most diverse types of riders.
