    SHIMANO GRX - Gravel Crankset - 2x11-speed

    SHIMANO's new FC-RX810-2 crank balances weight and efficiency for mixed-terrain riding. Gearing options cater for the specific demands of gravel riding and to maintain tighter gear steps for maintaining pedaling rhythm.

    • Gravel gear ratios preserve riding rhythm over rough surfaces with wider tires
    • 17T front range

    • Optimum gearing for mixed terrains and riding styles
    • Wider range front system
    • Gear combination: 48-31T


    Hollowtech 2
    24mm Diameter Axle

    HOLLOWTECH technology is an ultra-lightweight hollow crankarm created by SHIMANO with the company’s own proprietary forging technology that also maintains rigidity. The addition of HOLLOWTECH II technology integrates the bottom bracket axle with the right crankarm for more stiffness and a weight savings to achieve a high-dimensional balance. Its outboard bottom bracket bearing system provides better weight distribution and more pedaling stability, allowing for more efficient power transfer.

    HG-EV cassette sprocket is obtained 11-speed gear without compromising the 10-speed durability and improved HYPERGLIDE shifting.
