SHIMANO's new FC-RX810-2 crank balances weight and efficiency for mixed-terrain riding. Gearing options cater for the specific demands of gravel riding and to maintain tighter gear steps for maintaining pedaling rhythm. The 2x11-speed crank is available in a 48-31T chainring combination and 170, 172.5, and 175mm crank arm lengths.
Shimano's GRX cranks are designed to handle a wide variety of terrain and riding styles and feature a 2.5 mm wider chainline for more freedom in frame design and the use of wider tires.
The Hollowtech II GRX FC-RX810-2 crankset relies on a 2x11-speed drivetrain concept and offers the optimum gearing for every terrain and riding style thanks to Shimano's wide range of cassettes and sprocket ratios. The aluminium crank with a 46.9 mm chainline is characterized by the widest gradation of all Shimano components to date which is achieved by a 48 to 31 teeth chainring ratio. The 4-arm chainrings - made of aluminium as well - are compatible to HG-EV and HG-X11 chains.
