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.

Lightweight cranks reduce the total weight of the bike and above all the rotating mass which is decisive for acceleration. The challenge is to reduce the weight of the cranks without compromising stability and load capacity. Shimano's state-of-the-art forging technology offers an ideal solution with the Hollowtech cranks. Just like a high-quality frame tube, the hollow crankarm is extremely stable and resilient at a very low weight.

Hollowtech II
What matters is the overall balance of the crankset. With regard to the entire crankset, an optimum balance between the strength of the crankarms, the rigidity of the axle, the bearing position and other features is very important. When developing the crankset, the overall balance of all individual elements was carefully considered 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.
