Description

The new GRX FC-RX820-2 Shimano crank offers the perfect synthesis of low weight and high efficiency for riding on mixed terrain. The translation options address the specific requirements of gravel and ensure a consistent rhythm with narrower gradations.

The gravel-specific 2x12 option provides a tighter gradation of the rear cassette, ideal for fine cadence changes during competitions and fast-paced group weekend rides. And thanks to the use of the proven HG freehub body, the 2x12 setup can be perfectly combined with most existing 700c wheels.

Features:

Optimal gear ratio for different surfaces and different driving styles
Gear ratio tailored to gravel helps to maintain the riding rhythm even on uneven terrain with wider tires
Wide translation range at the front
17 teeth difference

Technologies:

HOLLOWTECH II - Perfect balance between stiffness, stability, weight and rotational efficiency

The concept of HOLLOWTECH II technology was aimed at producing an optimized crankset that minimizes the driver's effort for the drive. The high rigidity of the crankset ensures the efficiency of power transmission when pedaling, while its low weight relieves the strain on the rider, especially over longer distances. The crankset was developed with a view to achieving an optimal ratio between stiffness and low weight. HOLLOWTECH technology enables extremely lightweight, hollow crank arms manufactured using SHIMANO's exclusive forging technology to maintain maximum rigidity. In addition, the right crank of the HOLLOWTECH II set is firmly connected to the axis of the bottom bracket, which achieves an optimal balance between maximum rigidity and lowest weight. The externally mounted inner bearing offers better weight distribution and more stability, which ensures more efficient power transmission.
