With gravel and adventure riding becoming more and more popular, a groupset designed specifically for those enthusiasts was in dire need. The GRX Front derailleur is designed to handle a larger gear range, up to 17teeth difference between rings. You will also find larger tire clearance and more cable routing options depending on how your bike is configured. Furthermore, the shifting is easier and cable tension is adjustable on the fly for on-ride tweaking.

I switched out my old Ultegra crankset to GRX (FC-6800) as I wanted lower gearing. As I learned that the GRX chainline is slightly different and it would be difficult to keep the old Ultegra FD (FD-6800) from rubbing I also changed out the FD to this GRX810. It's important to find and download the Shimano installation and adjustment instructions as they don't come with the components any longer. Anyway, they made if very easy to install and to adjust to prevent rubbing at all chain angles.
The GRX FD-RX810 seems very much like the 105 FD-R7000 on my new road bike. It shifts quite nicely - smooth and easy. After 26K miles the old Ultegra FD was pretty beat up and ready to be replaced anyway.
