When the pavement ends and the real adventure begins, the Shimano GRX FC-RX600 1x Crankset answers the call. This is not your roadie’s crank—this is a front chainwheel born from the dust, rocks, and rough edges of the gravel frontier. With a 172.5mm crank arm length and a singular 40T ring, this unit strips away complexity and delivers raw, focused power where you need it most.

Every crank of the RX600 feels purposeful—stiff under load, silent over chatter, and intuitively balanced thanks to Shimano’s Hollowtech II construction. The 172.5mm arms are the goldilocks zone for most riders: long enough for leverage, short enough for optimal cadence, and ideal for long stints in the saddle when your legs are the only thing between you and the next ridgeline.

The single 40-tooth chainring cuts through the confusion of front derailleurs and dual-ring setups. No missed shifts. No front mech maintenance. Just you, your chain, and the right gear every time. This setup thrives on simplicity, and when paired with Shimano’s 11-speed wide-range cassettes, you’ll find plenty of climbing prowess and big-ring top-end for descents.

It’s also about the way this crankset feels off-road—solid, responsive, and designed with gravel-specific chain lines that improve chain retention and frame compatibility. Whether you’re loaded down for a bikepacking epic or slicing through a fast-and-loose gravel race, the RX600 is as versatile as your ambition.

This version comes in individual packaging (IND.PACK) and does not include bottom bracket parts, giving you the flexibility to match it with your preferred BB standard. The satin finish and purposeful design language make it look rugged, clean, and unmistakably GRX.

This is your ride's heartbeat—the bridge between you and every unforgiving surface you’ll conquer. With the Shimano FC-RX600 172.5mm 40T Crankset, you're not just riding a new component. You’re choosing simplicity, precision, and freedom on every gravel grind.
