Shimano GRX RX810 2x11-speed road bike crankset

Shimano ’s GRX FC-RX810-2 2×11-speed crankset is a versatile, high-performance solution designed to meet the needs of gravel, cyclocross and road cyclists. This double-chainring crankset (e.g. 48–31 teeth) combines perfectly spaced gear ratios with optimum pedalling efficiency, allowing you to tackle both long flat sections and technical climbs with ease.

Thanks to HOLLOWTECH II technology, it offers increased stiffness whilst keeping weight under control, ensuring direct power transfer with every pedal stroke. Its wider chainline (~47 mm) is specifically designed to provide more space for the wide tyres found on modern gravel frames, whilst ensuring perfect compatibility with 2×11-speed drivetrains Shimano, and HG-EV/HG-X11 chains.
