Shimano GRX FC-RX600

Ready to tackle mixed-terrain riding, still offering the option of 1x or 2x set up, the Shimano GRX FC-RX600 gives off-road riders a wider ratio with tried and true Shimano shifting and reliability.

Gravel approved.

Listening to feedback from those who live and breathe the paths less traveled, Shimano developed a groupset that will tackle dirt and gravel and excel on singletrack track drop-bar machines. Without breaking the bank, the GRX- FCRX600 works perfectly with the GRX-11 speed range of components while remaining dependable even in muddy conditions.

Bikepacking ready. .

The wide gear ratio is optimized for bikepacking and touring excursions. Climb with confidence knowing you can steadily spin up sustained, steep inclines on your fully-loaded bikepacking rig while maintaining consistent pedaling rhythm.

When riding conditions turn less than favorable, the specifically designed chainrings, paired with GRX tooth profiles and pins ensure positive shifting regardless of dirt, dust, and mud.

Great Gravel 2x Crankset

For my new gravel build I installed Shimano's GRX 600 groupset with 2x Crank and I'm loving it. On my previous bike I had a Praxis 4832 crankset with Shimano 105 - not a fan. I've not had any chain drops and my chain doesn't get jammed in between front derailleur and crank as it did with the PraxisShimano set up. 4630 is great too - perfect gearing for gravel. 46 isn't too small for road riding and I appreciate the 30 on hills. I chose to go with RX 600 instead of RX 800 bc they don't make the latter in a 165. All in all I'm glad I waited for GRX to come out for my new build - it was worth getting a gravel specific groupset.

A Proper 2x Gravel Ratio

Good to see shimano finally launch a gravel line. My mechanic was able to rig my FD6800 front mech to work with this part in the meantime until I install the GRX when I do the yearly maintenance of the bike.

Perfect gearing, plus looks and works great

Installed this on my road bike two months ago and I couldn't be happier. I needed lower gears in order to keep my cadence up while hauling my big ass up the hills in this area. This 4630 crankset was the perfect solution. It works perfectly with the Ultegra 11 speed group and looks great too.
