Shimano GRX Crankset FC-RX600 1x11-Speed-40T (172.5mm)

Shimano GRX - Explore Beyond

Instead of telling gravel riders what they needed, Shimano asked them what they wanted for their offroad adventures. The result are the Shimano GRX components which represent the first series especially developed for riding on rough roads and through gravel. The Shimano GRX sets itself apart from the rest of the component world with its gravel specific ergonomics, optimized gearing options, rugged reliability as well as a quiet and stable drivetrain.

SHIMANO GRX - Gravel Crankset - 1x11-speed - 40T - 172.5mm

Shimano's GRX cranks are designed to handle a wide variety of terrain and riding styles and feature a 2.5 mm wider chainline for more freedom in frame design and the use of wider tires.

The 2-piece GRX FC-RX600-1 crankset relies on a 1x11-speed drivetrain concept and offers the optimum gearing for every terrain and riding style thanks to Shimano's wide range of cassettes and sprocket ratios. The aluminium crank with a 50.1 mm chainline features a 40 teeth chainring and is suitable for the use with HG-EV and HG-X11 chains.

It is available with a 40T chainring and 170, 172.5, and 175mm crank arm lengths.
