I had an Ultegra 50/34 on my gravel bike and the overall gearing was slightly high for my riding style. This 46/30 makes the climbs a little easier and the high range is still sufficient. The GRX derailleur is a safe choice for full compatibility (make sure to follow the instructions carefully) though I did find some forum posts where folks got their older ones to work.

Only 200 miles on it, but it works well with the rest of the Ultegra drive train. At my age, I love the 46/30 chainrings!
