Reviews
I purchase the GRX specifically because it allows more gear options than the Ultegra derailleur. you can use the 10 and 11 gears on my 11-42 cassette and still be on the large front chainring. This cannot be done with the road version.
Just upgrade my bike from GRX mechanical to GRX Di2 and absolutely love it. Front derailleur is crisp and always a perfect shift. I have eTap on my other bike and this is amazingly faster.
Perfect for gravel and road. I take my gravel on some crazy "dirt" road and the GRX performs flawlessly. I love the automation of the trim so there isn't any chain rube. It's high quality as I've been through many components for all my years of riding. Recommend to anyone sitting on the fence.
