Product Description:


Shimano GRX – United in Gravel

Gravel is the great equalizer. No matter who you are, where you come from or where you want to go. Gravel celebrates individuality. It welds together in a shared passion. It lays the foundation for friendships and creates memories for the ages. Whether you ride one kilometer or a hundred. Whether with professional equipment or without. With a 10-speed, 11-speed or 12-speed gear system. Whether on paved roads, forest roads, back roads – or no roads at all. It does not matter why you are out there, all that matters is that you are.

Shimano GRX FC-RX610-1 crankset

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.
