Shimano GRX RX810 1x11-speed road bike crankset

The Shimano FC-RX810-1 crankset is part of the brand-new GRX groupset designed specifically for gravel riding. It combines light weight and efficiency for cycling on mixed terrain, including road and gravel. The gear ratios offered meet the specific requirements of gravel riding and allow for closer ratios to maintain pedalling rhythm.

The 1x11-speed crankset is available with a choice of two chainrings, 42T or 40T, and in crank lengths of 170, 172.5 and 175 mm.

The use of Hollowtech II technology optimises the weight-to-stiffness ratio of this new crankset, a process that allows for the design of a hollow crankset, retaining only the material necessary for the strength and stiffness of the assembly!

The Shimano GRX groupset stands out with its specific Gravel components: Gravel ergonomics, optimised gear-changing options, reliability, and a quiet, stable drivetrain. Shimano states that this is not a reworked version of its road components, but rather a groupset specifically adapted to the demands of Gravel riding.
