ROSE Bikes GRX FD-RX820 12-Speed Front Derailleur Braze On| Braze-on Front Derailleurs

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!

Just like the GRX cranksets, the GRX FD-RX820 12-speed front derailleur is optimised for a 47 mm chainline to provide space for large-volume tyres that can often be found on modern cross, gravel and commuter bikes. In addition, the RX820 front derailleur is designed to work with the giant 17-tooth front difference of SHIMANO’s GRX cranksets.
