Crafted with precision materials and innovative engineering, this 11-speed crankset combines durability, efficiency, and sleek style to elevate your riding experience on mixed terrains.

Materials & Construction

Designed with Shimano's high-strength aluminum alloy, the FC-RX810-1 crankset offers a lightweight yet robust build that withstands the rigors of gravel and adventure cycling. The Shimano Hollowtech II spindle ensures optimal stiffness and power transfer, allowing you to ride with confidence on challenging trails or long-distance gravel routes.

Engineered for precision and smooth shifting, this crankset features tighter gear steps for maintaining a consistent rhythm on familiar routes and varied terrains.

Components & Technology

Designed expressly for use with Shimano GRX Di2 electronic shifting components, this crankset enhances shifting accuracy and responsiveness. The 110mm bolt circle diameter (BCD) and Shimano Hollowtech II interface prevent flex and ensure a solid, reliable connection with your chainring, delivering a seamless power transfer. The single, 42-tooth chainring is engineered for durability and efficient chain engagement in mixed terrain conditions.

Style & Use Case

The sleek black finish complements any gravel or adventure bike, combining style with functionality. Whether you're tackling rugged trails, long gravel road rides, or bikepacking expeditions, this crankset provides the performance and reliability needed for demanding riding environments. Its clean, minimalist design fits seamlessly into your gravel bike's overall aesthetic, making it a perfect upgrade for serious cyclists.
