For your riding freedom: the Gravel GRX 1x12-speed FC-RX820-1 crank 44 teeth from Shimano
The SHIMANO FC-RX820-1 crankset combines durability, low weight, protection against mud and numerous gear ratio options to meet the different riding requirements of mixed terrain. By combining a 10-45 or 10-51 cassette with 40-, 42-, 44- and 46-tooth chainrings, there is plenty of choice between narrower gear steps or an ultimate range. The FC-RX820-1 is available with crank arm lengths of 160, 165, 170, 172.5 and 175 mm, offering fit options for riders of all sizes.
Both 1x12 options use Micro Spline, Shimano's lightweight aluminium freehub design that pairs seamlessly with a small 10-tooth sprocket and features smaller, more widely spaced teeth to reduce sprocket wear. The 1x12 gravel crankset is offered in three crank arm lengths, so you can choose the ideal Shimano GRX setup for your needs and riding style.

Technologies
HOLLOWTECH II - Perfect balance between stiffness, stability, weight and rotational efficiency
The HOLLOWTECH II technology concept was designed to produce an optimised crankset that minimises the effort required by the rider for the drivetrain. The high rigidity of the crankset ensures efficient power transmission when pedalling, while its low weight takes the strain off the rider, especially on longer journeys. The crankset was developed with a view to optimising the ratio between stiffness and low weight. HOLLOWTECH technology enables extremely light, hollow crankarms that are manufactured using SHIMANO's exclusive forging technology to maximise stiffness. In addition, the HOLLOWTECH II crankset has the right crank firmly connected to the axle of the bottom bracket, which achieves an optimum balance between maximum stiffness and minimum weight. The externally mounted bottom bracket offers better weight distribution and more stability, which ensures more efficient power transmission.
