Shimano GRX FC-RX600 Crankset

Gravel bikes are here to stay, and anyone who says otherwise has Shimano to answer to. The Shimano GRX gravel bike groupset adapts typical Shimano road technologies to mixed-terrain use. One of the most important components of any road adoption to gravel is the inclusion of a wide gear range. The Shimano GRX FC-RX600 Crankset takes care of that and then some.

A 46-30t chainring option has a similar jump in cadence to a compact crankset, but gears down to provide riders a lower gear when the going gets tough. Paired to a wide-range 11-34t cassette, riders have close gearing near that of a SRAM Eagle drivetrain with far smaller jumps between each gear. A 1x-specific option allows for up to an 11-42t cassette in the back. Besides that, all GRX cranks move the chain line out by 2.5 mm to accommodate a front derailleur and wider tires compared to typical Shimano road cranks.

The Shimano GRX FC-RX600 Crankset is available in four lengths (165 mm - 175 mm) in 46-30t gearing or 1x gearing options in 40t and 42t options. It is optimized for 11-speed drivetrains and is about 100 grams heavier than a GRX FC-RX810 crankset. Chainring BCD is not compatible with Shimano road four-bolt chainrings.
