Shimano GRX FC-RX810-1 crankset - 1x11-speed for mixed terrain
The Shimano GRX FC-RX810-1 crank offers you optimal performance on mixed surfaces and riding styles. Narrower gear increments allow you to keep the pedal rhythm on any terrain. A 2.5 mm outer chainline ensures compatibility with wider tyres. The single chainring features Shimano's Dynamic Chain Engagement technology so you don't have to worry about the chain dropping. Of course, the FC-RX810-1 crankset is also based on the Hollowtech II system, which has been tried and tested for years.

A lightweight crankset not only reduces the bike's weight, but decreases rotating mass to aid in acceleration. The challenge is to reduce the weight of the crank without reducing its strength and rigidity. Shimano's advanced forging technology has solved the problem through the Hollowtech crank. Just like high quality frame tubing, a hollow crank arm can provide amazing strength and rigidity at very light weight.
What matters is the overall balance of the crankset. With regard to the entire crankset, an optimum ratio between the strength of the crank arms, the stiffness of the axle, the bearing position and other features is very important. During the development of the crankset, the overall balance of all individual elements was carefully considered in order to ensure maximum stability.
Outer bearing: On most 68 mm bottom bracket housings, the Hollowtech II 24 mm axle can be mounted outside the frame for better weight distribution and stability.
High-quality precision seals: The Hollowtech II set also features high quality precision seals in the bearing area to extend durability and maintain excellent rotation efficiency over time.
The axle and the 24 mm diameter bearings ensure optimum balance of the crankset and optimum transmission of power to the bicycle.
