Crankset Shimano GRX FC-RX810-1 (1x11-speed)

Shimano GRX FC-RX810-1 is purpose-built for gravel and mixed-terrain riding, balancing low weight with maximum efficiency. As a core component of Shimano’s gravel-specific GRX range, it delivers reliable and smooth power transfer on rough roads and long gravel adventures.

The 1x11 configuration with a choice of 40T or 42T chainring provides optimised gearing for varied riding conditions. Tighter gear steps help maintain a consistent cadence whether riding familiar routes or racing. The HOLLOWTECH II construction ensures excellent stiffness and efficient power delivery under load.

A 49.7 mm chainline and 151 mm Q-factor are optimised for wider tyres and gravel frame geometry, offering improved stability and control. The 4-arm 110 mm BCD design and compatibility with HG-EV and HG-X11 chains make this crankset a versatile and dependable choice for gravel riders.
