GRX 2x12 gravel crankset
Shimano GRX FC-RX610-2 Crankset
The 600-level GRX double crankset brings 12-speed gravel gearing to more affordable builds, with a compact 46-30T pairing for big days on mixed terrain and loaded touring.
Highlights
Why we rate it
Low climbing gears
A 30T inner ring gives a genuinely easy bottom gear for steep tracks, bikepacking loads and tired legs.
Gravel chainline
The 47mm chainline matches the RX820 double for consistent shifting and frame clearance.
Two-piece Hollowtech II
A 24mm axle and outboard bearings keep the crank stiff and easy to service.
Value 12-speed upgrade
Works with the GRX 12-speed front derailleurs, mechanical or Di2, at a lower cost than the 800 series.
