  • Description

    Shimano GRX FC-RX810-2 2x11-speed Crank 48/31

    The new GRX GRX FC-RX810-2 Hollowtech II crank from Shimano was developed for 2x11-speed to handle a wide variety of terrain and driving styles.

    For gravel, road and cyclocross use: Shimano GRX 2x11-speed FC-RX810 Crank 48/31T

    All versions feature a 2.5mm wider chain line that gives more space in the frame design and wider tyres. GRX 1-speed cranks minimize the complexity of shifting only at the rear of the cassette (optional RX800/600 40T cassettes or RX800 42T cassettes), and are equipped with chainrings with SHIMANO's DYNAMIC CHAIN ENGAGEMENT+ toothed treads that provide optimal chain retention especially on bumpy surfaces. The GRX RX810 2-speed crank, on the other hand, is characterised by the specific 17-tooth difference between the large 48T and small 31T chainrings, the widest gradation of all SHIMANO components to date. Together with the 46-30T cranks of the RX600 series (10-speed and 11-speed), the 2-speed cranks of the GRX family thus offer more than enough bandwidth for super steep climbs and high speeds in the flat or on descents.

    SHIMANO's GRX, the first Gravel-specific component family designed for both fast progress and safe bike handling on loose surfaces, is the result of an intensive and extensive research, testing and development process that incorporates information and feedback from countless riders on trails, forest tracks, gravel tracks and asphalt all over the world.

    Technologies

    HOLLOWTECH II - Providing the best balance of stiffness, strength, weight and rotating performance
    The concept of HOLLOWTECH II technology is focused on producing a superior crankset which will maximize a rider’s power transfer. The rigidity of the crankset ensures pedaling efficiency while its weight, a key element of the crankset, you want light, aids in cycling longer distances over which the rider needs to pedal more. Naturally, SHIMANO strove for the optimum balance between the conflicting needs of stiffness while producing a lightweight crank. 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.
