Shimano GRX FC-RX810-1 42T 175mm Crankset

With this Shimano GRX RX810 Cyclocross & Gravel Crank, you get even more opportunities to explore rough terrain! This crank is light, robust and shifts quickly. This gives you one optimal support while cyclo-crossing or riding on gravel roads. Optimal resistance The gearing of this crank is adapted to cyclocross and gravel riding. The 31-tooth internal blade of the double will allow you to climb almost any climb and the 48-tooth outer blade gives you plenty of options on the flat. There's also the option of a single top sprocket, which the keen cyclist and gravel enthusiast will appreciate. Low weight and smooth shifting This crank is made from lightweight materials, with as much 'useless' material as possible removed. The cogs on the cassette are precision engineered to give you smooth and fast gear changes even in extreme conditions. Only works with 11-speed GRX Front Derailleur The double-crank has a big difference between the inner and outer ring. The cage of the GRX front derailleurs has a special shape to accommodate this. These GRX front derailleurs are the RX810 and RX815 front derailleurs.
