Built for the roughest backroads, steepest climbs, and wildest adventures, the Shimano GRX FC-RX600 Crankset (175mm, 46-30T) is the powerhouse of gravel riding. It's not just a front chainwheel—it's the rugged, gravel-tuned heart of a drivetrain that doesn't flinch when conditions go from smooth to savage.
Designed to pair perfectly with 11-speed rear setups, the FC-RX600 brings Shimano’s gravel-specific engineering to life through a meticulously calculated 46-30T chainring combination. This gear range strikes a critical balance: fast and efficient on open roads with the 46T outer ring, and strong, climb-friendly with the 30T inner ring for when the road becomes a loose, steep, or unpredictable challenge.
The 175mm crank arm length gives riders with longer legs or those seeking optimal torque leverage an edge—more power per pedal stroke, greater climbing force, and increased control over mixed surfaces. This extended crank arm amplifies your strength, especially during long days on the bike, steep gradients, or loaded bikepacking rides.
Constructed as a 2-piece FC (Front Chainwheel) with Hollowtech II technology, this crankset is stiff where you need it, light where you want it, and reliable where it matters most. The outboard bottom bracket compatibility (sold separately) ensures wide bearing stance and improved stiffness, making every push efficient and smooth. Whether you’re tackling backcountry trails, fire roads, or gravel races, the RX600 responds with dependable power transfer and terrain-tested durability.
Shimano’s GRX line isn’t road rebranded—it’s purpose-built for gravel. That’s why this crankset features a wider chainline and optimized front shifting for off-road cadence transitions. Even under load, with mud or dust in the mix, it stays sharp, precise, and fluid. The low-profile design further enhances ground clearance and helps maintain momentum through rock gardens, roots, or washboard sections.
Shipped in individual packaging (IND.PACK) and without bottom bracket parts, the FC-RX600 offers the flexibility to tailor it to your specific build, making it ideal for replacement, custom frames, or performance upgrades.
