The introduction of the Shimano GRX group is a big deal. Not just because it’s the industry’s first groupset designed specifically for gravel riding and racing but also because it’s the first time Shimano offers a dedicated 1x crankset outside of their mountain bike lineup. For riders seeking the simplicity reliability and improved chain retention of a single-ring drivetrain on their gravel or all-road bike look no further than the GRX FC-RX600 1x Crankset. As you might’ve guessed it’s designed to work with Shimano’s GRX 11-speed gravel group. That being said it would work just as well if you wanted to throw it on your existing bike that’s already equipped with Shimano 11-speed road components. Shimano spent over two years getting feedback from gravel enthusiasts when developing the groupset that will ultimately tackle dirt and gravel roads and singletrack on drop-bar machines. It learned that rider’s wanted the option of 1 or 2x setups wide gear ranges with low enough gears to tackle tough climbs and of course reliability. The GRX FC-RX600 gives you all this and works flawlessly with the rest of the GRX 11-speed lineup. It also comes in at a much more palatable price than the premium GRX RX810 cranks albeit with a modest 100g weight penalty. The crank is constructed of durable lightweight and stiff aluminum alloy and is equipped with a 40t chainring that provides the low gearing needed for tackling tough climbs without sacrificing too much top end speed when you’ve got a long descent ahead with a tailwind at your back. This is accomplished in part by specially engineered tooth profiles that ensures positive shifting without the risk of dropping your chain even in muddy and dusty conditions.
