ROSE Bikes GRX FC-RX610-2 Hollowtech II Crankset 2 x 12-speed, 30-46 Teeth| Road And Cross

United in Gravel!
With a clear focus on the heart and soul of gravel biking, SHIMANO’s mechanical GRX series now gets a 12-speed update to deliver top performance!
Simplicity and reliability build the basis for the new 12-speed GRX line-up and allow you to enjoy off-road adventures of a special kind!

While developing the GRX FC-RX610 double crankset, SHIMANO’s developers have paid particular attention to the needs of modern cross, gravel and commuter bikes.
For those who appreciate versatility and flexibility, the 2 x 12-speed version of the RX610 is an excellent choice. A gear ratio of 46/30 teeth chainrings, which is optimised for gravel use, is used on the crankset in combination with 11-34 or 11-36 teeth cassettes. This configuration provides an enormous gear range, which at the same time guarantees a comfortable cadence – when cruising on the flat, on long gravel roads or in the mountains.
